[Karns Performance]

hello jason, I put the link at 138mm like yours and I removed the 6,5mm fork, I like the bike like that, much more agile than before, it just ripped the rear tire a little ....... in powerful braking it moves a little further back ..... the electronic gearbox and the blipper are not so efficient .....
if you have other tips for track use ;-)

i have not had issues on the track with the shifter/blipper
