Quote:[/align] This kit (known as a Stage I) lowers your final drive ratio about 10% through the sprocket sizes. So, that means you will increase your rpm's by about 10%, reach your shift points much faster, accelerate much harder, and reach your top speed much quicker. Because the Stage I doesn't increase your rpm's so much that you will reach the revlimiter in top gear, your top speed won't be effected. And, in fact, on some bikes that are geared on the high side from the factory, OR when the rider weights 190+, the kit can actually increase your terminal velocity by allowing your engine to rev higher in top gear, creating more hp, and help overcome the natural rolling and wind resistances.

is this true?

A "quick acceleration" sprocket/chain conversion will be the best bang for the buck, but you do loose a bit of your top end speed (not to mention highway riding will be at a higher RPM).

 

+1 on sprockets. Top speed is a non-issue for most people so aside from maybe losing a few MPG, there is no downside.

 

any sprocket recomendations? for better acceleration and less loss of top end

btw what is +1 lol

 

the +1 is sprocket teeth
-1 is minus 1 tooth
+1 is plus 1 tooth

so a -1/+1
is minus 1 on the front sprocket and plus 1 on the rear sprocket.

that is a popular mod
quicker take off without sacrificing too much top end

for even better handling go with a 520 conversion with hardened AL sprockets as well.
you can save a few pounds of rotating mass that way.

brands like AFAM, sprocket specialist, renthal, and Driven are the best out there.
stay away from non hardened AL. they wear out real fast.

for chains DID ERV3 is top notch and stronger than oem

 

whats an estimate percentage of a diffrence 5 10%?

and thanks for the help guys!

 

Your best gains you will get from aracing school, trackday.

The bike already has way more performance right out of the box than you will ever be able to coax out of it, So your best bet is to improve the rider, before trying to improve the machine.

 

ok thanks I was actually looking into going to track school so I can learn to lean better.. the only time I speed really fast like over 100 is on a long stretch of road I don't take corners faster than 60.. lol

 

^^ more the reason to take a good superbike school.

I took the level i course through California Superbike School at Laguna Seca. It was absolutely the most incredible thing I've ever done, really. Well worth the $650 (to ride their bikes) or a cool $450 to ride your own. Doing it again in April..........it's that addicting.

 

its not about power, its about where the available power is at. we all know that a gearing change does nothing to horsepower but moves the available hp around. this is a great mod for the track especially for novices because a tendency is to try and take a corner in too high a gear. if it is geared down then the results are muted. the change in gearing will help compensate for too high a gear.
