Hey whats up i wanted more speed so i was thinking of getting smaller front sprocket, what type of speed will this give me off the line? alot more power?
How much top end will i lose? like 5mph?
THANKS!
Sprockets work on ratios. Do you remember your fractions in math class? If you change your 14 tooth front to 13 tooth, then your top speed drops to 13/14ths of what it was. Or another way to look at it is that your highway RPM's increase to 14/13th's of what they were before. So if your top speed was 114MPH, now it's 114*13/14=106MPH. And if your tach said 8,600RPM's at 70MPH, now it is 9,300RPM's.
Some people say that the 13 tooth sprocket helps off the line. Personally I doubt it's much benefit. You will get going quicker, but then you have to shift, and that eats into your acceleration.
Like 1Adam12 said, changing sprockets won't add any power to the bike. It will only change where you have your power (off the line or on the highway). I like the bigger sprocket up front to decrease highway RPM's.
And like 1Adam12 said, adding K&N pods and rejetting will give you an extra 1-2HP.
