I just got the full power bundle and vibration dampers for the 2025 500 EXCF. Not only was it very cost effective, but the performance of all the parts honestly exceeded expectations. Use this as a testimonial if you want. "Hey everyone and any doubters, there is NOTHING you can spend money on that's better than this kit and these handlebar dampers."

Yes. Most impressive! The occasional stalling out when cold on take off no longer happens. Much smoother overall with a little more 'umphh' in the low to mid ranges. Best bang for the buck out there, and dyno verified. What's not to like.

Yes, I did notice a performance increase with all the BDSB products installed. The muffler end cap was the first BDSB mod installed to a stock bike, except for a JD Jetting Fuel Programmer. Performance and sound were an immediate improvement. The BDSB fuel rail made the bike more responsive. The BDSB big bottom kit was felt at higher speeds in 2nd, 3rd, and 4th, when throttle is hit hard. The bike is uncorked with intake reeds removed & JD Jetting Fuel Programmer. The imprecise chatter from the clones on the web says “snake oil!” The products work for me and I would not purchase them if the products did not work. The products work!

When I bought my 500EXC in 2018 I had just gotten off of a 2014 350EXC and I was expecting an order of magnitude difference in power. Well, that was hardly the case. Shiny and new, sure, but I was... quite disappointed. I installed the full fuel programmer kit (rails, end cap, manifold) within a month and 4.5 years later it's still be best upgrade I've ever done on a bike. The 500 is a beast uncorked, but most programmers don't come close in sophistication. I ride the bike daily at an altitude of 7000ft, often going up as high as 10k and it roars. Not a crack or pop anywhere, neither lean nor rich, just right. After all this time, at 12,000 miles it's as strong as ever. The kit has more than proven itself in power and reliability. Definitely putting one on my next KTM.

I trust their recommendations and videos. Performance is always spit on! I think the only part I don't have is the new heavy duty oil plug magnet, that will be next.

I got out and ripped it today on two identical southern california loops , here’s what I found.
The Coober and Pin It are both real good but I give the nod to Pin It

The Coober stutters just a tad at even cruising throttle and it hesitates just a tad when I’m blipping it through whoops or hitting jumps coming out of corners on trail.
The idle is decent.
The Coober pulls harder at wide open higher rpm’s.

The Pin It idles better , lugs better down low , has no stutter or hesitation anywhere. It just runs fantastic.
Dare I say my bike runs perfect with that ecu.
Not to mention the price is way better.

I’m totally willing to send you my Coober so you can test it against Yours.
I would love to see that video and results.

Thanks Dave !

It is a dramatic difference! I was shifting around 4000rpm and carrying a gear or two higher than I had before, using 6th frequently now. The sound is slightly louder with a bit more vibration but it easily cruises at 80mph without feeling that its near top speed. I have not opened the throttle fully as there is no need, prior to the tuner I frequently hit the throttle stops. Mixed gravel road, back road and highway have returned 72mpg.

Hey, just wanted to give a quick update on testing.

John Murphy was the first rider to try them out. He installed the grunt manifold and fuel rail the day before Mini O’s down in Florida. He practiced a start to see if he could tell a difference and nearly looped out when he shifted to 3rd gear. That is on a bike that just had an ecu, fmf exhaust, and your parts! I asked him how it ran, and he replied “fast as ****”. He was pleasantly surprised with the results for how simple it was. Out of around 100 250 pro riders, John was 15th in timed qualifying, ran top ten in his heat race (7the place start), but had some bad luck in the main.

Next up I stuck the manifold on Tristan Falls’ new MC250F. In completely stock form, it helped tremendously on tighter tracks. I made this test more “blind” by pulling the bike in a box truck while swapping manifolds without him aware of what I changed. He knew I had purchased a ported cylinder head, and he thought I had installed that between rides. When we did test it with the ported cylinder head, we found that we could get the same bottom end with the manifold as we could with a 2016 intake boot and decked cylinder head. To me, that was great news, because I’d much rather achieve the results with the manifold than have to increase compression, tighten tolerances, and track down older air boots.

On the MC450F in stock form we were all kind of in-impressed with how smooth that bike is. The general consensus was we didn’t care what rpm we achieved it, we just wanted excitement somewhere. The manifold solved that! We’re currently running the manifold, the 9oz clutch weight, and a 14/52 gearing both to stretch the power out and free up the chassis.

When isolating the fuel rail on both 250&450 we couldn’t tell a difference in power, but didn’t experience flame-out like we had on off throttle scenarios with OEM components.

All in all, very pleased! We’d like to order another setup for the 250f.

Ive built my 500exc around most of the products offered by BDSM for 3 years now. I can say my bike is a complete BEAST and have been more than satisfied with the products Dave offers for our toys. It doesn't matter if I'm not in the right gear on climbs, if I input throttle, the bike pulls, hard. Fueling is on point!

Like many others I was very skeptical about the severe improvements the parts would make on my bike. It wasn’t until I watched every one of Dave’s YouTube videos that I gave it a chance. I started off slow with a few pieces and ended up buying nearly everything in the bike bundle if not more. The grunt exhaust manifold was the game changer for my bike as it wouldn’t wheelie easily out of the gate. Once I got that installed and later addressed the fuel related issues, I can’t keep the front end on the ground! Thank you for all your work and I will continue to buy and recommend your parts in the future.

Super happy with the bike’s performance! Even more happy with Dave’s responses, insights and advice. My ultimate compliment is for Dave standing behind his products and great customer service…Highly recommend Best Dual Sport Bikes!

I have used Dave’s parts on several bikes as projects now and would highly recommend the end cap for the exhaust and the injector relocator kit as it gives the TPI more throttle response and power. His fit and finish is absolutely some of the best I have seen. I was skeptical about the clutch weight but it does help with the low end chugg!

I have done several bikes with products from Dave. I have piece marked things in the past but I will tell you his stuff flat out works. The quality of his components is fantastic and the fit and finish is unbelievable.
After dealing with him personally as well I would highly recommend his stuff!!!!!

Installed the fuel package including fuel pump, filter, 90 degree connection, fuel rail
easy to install and works great with no flame outs at all!

Also, installed the Big Oily clutch cover, easy install and looks great! The added oil capacity is a good peace of mind especially on long rides with no oil changes.

Would like to mention that this company ships their products in a very well thought method of packaging to assure a safe arrival.

Thanks Dave for all your videos and expertise, it's been a huge help in producing my awesome KTM 500 !!!

The parts are great, machining is second to none ! I love the fuel filter much larger and more efficient, the fuel rail running straight in instead of two 90degree bends makes a lot of sense. If you put any miles on the pavement you need this wheel weigh, I tried different stick ons and others but this is clean, looks great and functional . The tank fitting is a must have stock one is to vulnerable.
Thanks Barry

Booster plug was an easy add on and does exactly what you said it does. Bike runs great and pulls much better in low rpm zone. Also added the foldable levers they are very nice. I also added a 14 tooth front sprocket. This is definitely a must have. Thanks for making good products at affordable prices

The Coober ecu made such a difference on my 300 paired with an RK Tek head. By far the best running 300 I have ever had which is something I never would have thought possible after I first bought the bike as it had very lack lustre unpredictable power through the bottom and mid. The ecu and head cleaned it right up. It does not sign off with my snow bike kit installed in the winter either. It pulls with the big 4strokes! I also Feel a lot better knowing I have the better fuel pump and filter in my tank on the longer in the middle of nowhere rides. Your videos are fantastic and easy to follow! Keep up the good work it’s appreciated.

Everything worked great for me.His Videos were a huge help as well.

Great quality and fit ,last filter you'll buy just take the screen out clean it with spray on brake cleaner and your riding for a long time without wasting time or money on the stock cheap junk. Every KTM, Husky and Gas Gas owner will be happy with your stuff. I HAD A CLOGGED FUEL FILTER THE OTHER DAY THE STOCK TINY INLINE ONE THATS OUTSIDE THE TANK, IM GLAD I BOUGHT THE FUEL BUNDLE FOR OUTSIDE THE TANK. I DIDNT INSTALL IT YET BUT THE MUCH BIGGER FILTER WILL TAKE YEARS TO CLOG IF EVER. THE 90 DEGREE ELBOW WILL MAKE THE GAS LINE FOLLOW THE BOTTOM OF THE OVERSIZE TANK I ALSO JUST GOT NICELY. THE INJECTION PART WILL GIVE THE BIKE MORE INSTANT THROTTLE RESPONSE. THANKS FOR GOOD INSTALL VIDEOS.

Very impressed with all the components and yes the power increase was excellent along with fuel air ratio, I also installed these products on my 2017 FX 450 with great results, my question is on a cold startup my 17 FE501 bike with vortex ECU will stall after about 20 seconds, once I restart it is fine, bike does this every time on cold start up, I can just about predict when it stalls, like it needs to reset itself?? Does anyone else have this issue?? My Only complaint.

BDSB products work as advertised. The best part is the correspondence via emails. If you want to know about an out of stock part or what do they think your bike issue could be, they'll respond to your email swiftly with no bullsh!t answers.

Throttle response was improved and haven’t had a flame out. The 90deg fuel rail because of the spout angle the stock fuel hose was kinked so had to get longer hose but other than that no complaints.

What a great products! Super easy installation, and gains better than expected the heavier clutch weight is a revalation, it seemed to flameout just when you needed it most, that is all but cured now, if I stall out now it was rider error!! The fueld delivery gives peace of mind to wide open throttle use, knowing its not going lean.

I’m 185 lbs, 6’-00”. I can now stand more comfortably without bending over so much on the dirt. Also more comfortable on the road. It’s seriously a different bike now. Fast shipping too. These risers are a necessity.

I believe that these are mandatory components for those people who need real power. This is necessary for those people who want to unlock the full potential of the motorcycle ! I'm from Russia and everything came on time .

Waaaaaaay better than stock. MUST HAVES!

Yes, performs well. Thanks for a great product!

My family gave me this power bundle for Christmas 2020. I was not too excited and thought it might be snake oil. I installed the kit January 2021 and realize how wrong I was. This kit solved my flameouts and gave me more low end. I was disappointed in my bike and now I love it. Some forums suggested all you had to do was drop a tooth and go to 13 on the front, this I did but it didn't solve the flameouts. I hold expert licenses in enduro, cross country, motocross, and road race I know bikes and what they can do. More low end, more high end, no flameouts, more horsepower, I now love this bike. Great product!!!!!!

The BDSB power bundle is a great value. With over 40 years of racing and building motorcycles I was skeptical of the performance claims but after installing the kit on my FE 450 it addressed all the Issues of the stock bike, flame out /stalling anemic power and overheating. I have been enjoying Extended dual sport rides all over the western United States for over two years now with the kit installed with no issues, the power gains were amazing. I have since installed the BDSB power bundle on a friends FE 250 with the same results. Thank You, Dave👍🏁 Scott Mays, OC Dualies & Flying Monkeys DS

I was hoping for an improvement to the stock exhaust note of my 390 ADV, which sounds more like a lawn tractor. The BDSB end cap made a huge improvement to the sound. Now, it sounds like a motorcycle.
The bonus was a noticeable improvement to the power delivery. Better throttle response, and more willingness to rev-out, above 8,000 RPMs. The engine seems to run a bit cooler, as well. A very effective improvement for only $100.

Bar risers very easy and big improvement


Exhaust cap a little more difficulty but once you have old cap off it’s pretty easy

Super happy with the larger filter. Throttle response feels better

End cap is great, I was hoping it would make the bike a lot quieter but it doesn’t seem to be much quieter, which I feel is something all the manufacturers should take care of from the start. Everyone is so worried about horsepower that most riders don’t even know what to do with instead of helping protect riding areas. Which is what we all need more of. My friends Ktm 450 with the akrapovic exhaust is so quiet and has all the power too. That’s what I was hoping for but maybe it’s the 350💁🏼‍♂️

The bloody bastard tried to stomp my guts out.!!

Honestly the power bundle transformed this bike , reduced flameouts runs better,
CheersD

All upgrades work as advertised, good stuff!

Quality product, as described. Installation was relatively straight forward - some mucking about with re-routing clutch cable etc. though not really surprising given you're moving the bars!

Was pleasantly surprised to find the added benefit of reduced vibration in the bars following installation. The riding ergonomics are greatly improved, less weight on the wrists when cruising and better position when standing.

Honestly, after I installed the power bundle on both bikes and rode them, I was actually a. bit mad. MAD AT KTM for making a bike that was SO choked up. The kits were amazing, and turned the bikes into exactly what they are supposed to be. Throttle response was instant, no flaming. out, and power gains across the board. So again shame on KTM ( or California ) for making these kits necessary, but necessary they ARE! Very happy with fit, finish, quality, and installation instructions. The 250 kit was a little more labor intensive with the fuel pump parts, but otherwise a piece of cake. Have recommended to many people so far. Seems expensive, until you do it, and then it seems totally reasonable... even REQUIRED.

Just like I added a super charger to the bike Works incredible

Here is what I can say about the upgrades I made to my bike: Want your 350 cc bike to have the power of a 450, and the feel of a 250? Don't wait another second! The power gain is immediate, and impressive. Not kidding about the power of a 450, with the feel of a 250. Every friend who rides my bike is blown away by the power and feel. Two friends purchase the same bike, going from 450s to 350s, so they could do the same upgrades. These upgrades are easy to make (2-3 hours to install everything, the hardest part being removal of the old end cap from the exiting stock muffler.

Items purchased were packaged and the web page had all the info I needed. I had ask the owner if he could sell me another fuel hose from pump to filter with the clamps and he just sent them to me. His video are very informative and they speak clearly and good pace so I can absorb what he’s saying.. I told a lot of the Husky and KTM riders in our groups about his products. Great service

Install of the 2 stage in tank fuel filter was relatively easy. Hardest part was muscling the fuel lines off of the old filter without damaging them. This in tank filter eliminates one of the problems with the stock setup, (the plastic Mahle filter), and potentially saves a very long walk home.
Thank You BDSB!

Radiator guards are a perfect fit and have provided excellent protection. Fuel programmer has offered great opportunities to dial-in performance for different venues such as desert racing vs. single track. I've logged different settings and can adjust the performance to match my style of riding and racing rather than me having to adjust my style to the dictated ECU performance.

Pump and filter kit comes with everything you need, unlike the competitor product.No need to source additional connectors and correctly sized hoses. A really big plus was the customer service side of the exchange: a defect was immediately resolved with no back and forth or escalation. That is top tier customer service and backing of the product. Thumbs up and gets a would buy again and would recommend.
