Unfortuately, there are no z8s for the front wheel. Michelin cant decide if they have the front tyres or not. I ended up with Bridgestones BT023s. The main problem is getting the right tyre for th front, as it drives the speedo and you want that correct.
The bigger rear drops the revs ar 100ks by 100, so no biggy, at least thats what my calculations show
