These are at the ceramic coaters now and schedled to ship between August 1st and 10th.

           Our header is ceramic coated, on the inside. This keeps heat in the header, instead of letting it boil the radiator.  This is a high performance header, with no catalytic converters. It weighs 2 lbs less than stock.  This, along with the stock "pre muffler" box, our exhaust end cap, and fuel programmer, produce the best "rideable" power, and sound, you'll get from your 390.    The last pic shows how close the hottest part of the exhaust, is from your radiator. That's why the fan is on so much

   Fits 2020-22   250 and 390 KTM Adventure and 2021-22  390 DUKE
