Hey guy's This is Jojo from Bama. I just bought my new 919 and I LOVE the
pepp in this bikes throttle between 5 and 9 grand on the tach. My front tire always gets a few inches off the ground! But thats what I wanted to start this forum on. Since the bike has 9,500 on it I will need to put a chain and sprocket on soon. Anyone have any suggestions on what to use? I know i'll use DID znm series premium but is there any validity in going up or down in sprocket size? I've never done that before. And Which is the best tire for the curves? The Power pilots on the rear and the road pilots on the fromt or just go Perelli Diablo Corsa III all the way? What will a 120/65 front feel like on this bike? Thanks for all your imput! I'm lovin my Hornet.
If you are wanting more wheelies you can go with a 15/45 sprocket combo, but that will sacrifice your top speed.
Tires come down to preference, everyone has their own opinions. Do a search on tires. It is a matter of how many curves you are taking and if you intend to go straight. Also what kind of life you out of your tires. I personally love Pirelli, and they have yet to fail me. I have ran Strada rear tire, and it is lasting a pretty long time, and grips great. Pirelli Rosso front and its awesome. My friend ran a Rosso rear on his SV before selling it and it will probably be my next rear tire. Also look into Michelin Road 2ct tires for long life.
Welcome!! Glad you're enjoying your Hornet. It'll provide you many miles of smiles!!!!
As stated above tires seem to be a very personal choice. I had Pilot Powers on my last bike and loved them, and still have the stock tires on my new 919, although I haven't had a chance to get out and get a good feel for them yet. Those are the only tires I've used so I can't give you an educated answer on different tire choices.
Stock gearing is a really good starting point. Most people will never need to change it. Going smaller on the front sprocket and larger on the rear will give you better launch, but you'll sacrifice some top end, and freeway riding will get a little buzzier. The opposite is true with larger front and smaller rear sprockets. Again, every rider knows what they like, so the gearing I choose may not work best for you and vice versa. Front sprockets are cheap and easy to change, go experiment and have fun!
