Hello everyone,
I ride a birel art KZ with a black r2 in france, red rear axle, front std middle, and rear at the very bottom with 2 stiffeners on each side, the problem is that I weigh 90kg and some and I am missing a little front and the rear which sticks too much, do you have any solutions?
First switch to a yellow axle, the red one is a hard one. This will free up the back.
Hello thanks you but with yellow I have more rear
Birel recommends a stiffer axle to free the rear and a softer to provide more grip.
They provide a pretty good setup guide and axle chart, I would print these off and hang them in your trailer or keep them handy on your phone.
yes, I already had that, so I guess the green axis would be a good idea to re-regidify it to the max? to slide a little more and have less understeer
Is everything else set to factory standard? Seat position? Caster/camber? Stub axles? Front width?
What tire compound are you running?
Generally the BirelArt baseline will get you very close.
