14 Tooth front sprocket question - SV650.org

24-03-10, 01:15 PM

I recall seeing a few threads with them mentioned, I'd like to change the gearing slightly and seeing as my C&S are due for replacement at the start of the decent weather it seemed like a good opportunity to try it out.

Questions are:
1: is 14t the sensible way of going about it or should I add 3 to the rear?
1a: if I go for the 48t (the stock is 45 right?) do I need more chain links?
2: O ring or X ring? last time I was looking most people thought o-ring.
3: Does Steve of F&B Tyres sort out the whole C&S set or do I need to supply them for him to fit?

Any other relevant advice much appreciated.

i normally go 1 down on the front, gives better acceleration, and a tad less top speed...remember ur speedo will read wrong..and o ring

Yup speedo sensor on wheel so that should be fine.
unless anyone has any 14 tooth horror stories of lack of chain life then I'll start looking around for the parts.

I would advise going up at the back instead, going down at the front increases chain wear and wear on swingarm slider.

never had any bother on super tuned bandit 12's with one down on front,...and ive done plenty

Some other people would disagree.

It's a fact that going down on the front increases the chain tension for a given wheel torque. whereas going up at the back increases wheel torque for a given chain tension.

yup heard the pro's/con's...all im saying is ive never had any probs...i was national rep for the bandit owners club, so did loads...no issues, but as u say i have seen worn away chain sliders'..mainly on 7/11 fighters

How many miles does average 7/11 do?
