Hi guys, so winters coming so im guna start cleaning and doing the bike up.

just look to start with chain & sprocket change as it seems really loose and i cant seem to get the chain back any more.

(Just done my oil filter and oil change)


So should I go for off the line speed or top end?

im feeling the off the line to be honest. wheelie machine would be nice, as it was a reasonable cheap bike so I would like to learn to wheelie before i get a RR next year :P (will of course be done on my own private property in a controlled environment)



So can anyone recommend a good setup, also i dont quite understand how it works do extra teeth on the front and less on the back make it quicker off the line but slower top end and the other way round is vice versa so slower off the line and higher top end?


as mcuh info would be great, keeping it simple to start off with to start off with would be helpful but i am fine with research anythign you say that i done understand or i will ask


thanks guys

 

I found that mine would wheelie just fine when it was bone stock. FWIW.

As far as the gearing theory, if you reduce the teeth at the wheel you are spinning the rear wheel faster for every revolution of the engine. Keep in mind that the number of links stays the same for a given time period. Smaller sprocket then means that the same number of links is further around the circle.

Same thing only backwards for the transmission sprocket. Increase the number of teeth and you are moving more links for the same rotation of the sprocket. More links, more of a circle when you get to the back wheel.

I am a math teacher and we actually did a unit on this in one of the classes I taught. I took in an old Harley belt and a front and rear sprocket and we painted marks on the sprockets to see what was happening. It was quite fun.

 

spoke to Demon Tweeks (UK company) and they recommended the following:

Tsubaki Alpha X Ring Gold Chain

Rental Front Sprocket -1 tooth

Supersprox Stealth Rear Sprocket


from what I have seen on the forum that should be a good set up, what do you lot think?

 

You want acceleration off the line go smaller front larger rear

You want more top speed go larger front smaller rear.


To be honest with you it doesnt change your final drive ratio THAT much, you may see 1/4 to 1/2 a second difference in your 1/4 mile times.

I have a -1 front currently and my highway rpm is fine, im thinking of upgrading to a +1 rear.

 

went for:

Tsubaki Alpha X Ring Gold Chain

Rental Front Sprocket -1 tooth

Renthal Rear Sprocket


now fitted, rides beautifully now.

 

The Gearing Commander website will tell you how different size sprockets will change your top speed and rpm. Load your bike's stock setup from the drop-down menu and tinker away.

As far as understanding how it all works think about the gearing on a bicycle. When you shift into a larger sprocket on the rear it makes it easier to pedal. When you shift into a smaller rear sprocket it is harder to pedal but you'll go faster if you're still turning the cranks at the same rpm. Things are just the opposite for the front sprockets (chainrings).

 

Ye i used that site and all it done was told me my bike would be slower through every gear SPEED wise. gave no indication as to how the acceleration would be increased.

 

a widdle bit

 

how often do you ride faster than 55? next chain and sprockets i'm going back to stock setup. the high rpms at highway speeds gets annoying, and i'm always trying to shift into 7nth gear.

 

GIPRO gear indicator. It helped me with my 7th gear problem.
