Youtube SealMate then you either buy a SealMate or you make your own and clean your own fork seals. My right one leaked and i simply made my own sealmate, cleaned the dirt that made the fork leak and badda bing badda boom
It’s a fraction behind the KTM in terms of performance, with 99 hp at 9,000 rpm instead of 105 hp, and 60 lb.-ft. of torque at 8,000 rpm, down from 64 lb.-ft. for the 790 Duke. Manual says 9300 miles or every year. I won't put that many miles on it in a year so it's every Spring for me. Agreed!! I used to change mine about every 3k mi or so, though like JD said, when I start to feel a lack of smoothness too it's time. wJpcmt. 442 91 157 239 120 396 339 168 460
