Hello fellow riders. I have just got my full bike license after a painful year of having to ride my silver slug ( Suzuki gsx 250 across) My new ride is a 2007 FZ6S Yamaha. I believe it has the retuned R6 engine so it probaly puts out 70kws. ? My local bike mechanic is going to install a after-market air filter. power commander and do the dyno for it. The only question is what after market slip on will give this bike its full potential and is it worth it paying more for carbon fibre tips on a exhaust?
