Im installing a 520 conversion on the bike, will this affect the computer at all I know if you change tires it has to go for such a distance to get used to the new stuff are sprocket changes similar ? and if so what do I need to do. Thanks. :bangwall:

Do you have a 2011 aPRC bike? If so, then you have to calibrate the traction control system I believe. If it is a 2010, then you won't need to do a thing. The speed sensor reads off the rear rotor so your speedometer should be still alright.

yes you have to calibrate, go to menu go to calibrate ride bike in second gear at 23 mph until calibrate goes out on dash hope this helps !

Youve been a big help , this thing is a lot different than my previous bike. Im gonna change to a 15/42 setup with a 520 chain to drop some weight , the main reason though is the extremely tall gearing on this thing. Been riding since 1980 and this bike has the tallest gearing ive ever ridden.

I think you will find that the tall gearing is for sound checks.
I was told the Italians gear them tall so as not to turn as many RPMs to keep them quieter for sound "homoligation" in Europe.

and I read that its because you cannot change the transmission innerds, only sprockets, if you want to race in a production class, sure makes sense

I guess you wont find the loud pipes save lives sticker in europe. I used to have one back in the day on the back of my old KZ1000R , the baffle blew out of the old kerker muffler one day riding home from school so I bought a jet kit and went with it. I kinda miss that bike. With the gearing on there now you could probably run it at bonneville lol.
