I need max exposure for some quick responses.

Just had a call from the garage where my 01 748S is being serviced. It needs a new Chain and Sprocket set.

My question is, would I benefit from lowering the gearing by upping the teeth on the rear?

Has anyone done this out there? I have done a search but cannot find a definitive answer for the 748S.

They have to order the set in and I want to phone them first thing tomorrow to let them know if I want to change from the standard set-up. Hopefully avoid messing them about.

The thought only came to me after the shop had shut for the day.

Any quick advice much appreciated.

Churz - Jacko.

Loadsa people done it. Don't know about best combination of front & rear sprockets but long and short of it is -

1. choose whether to change the front sprocket (down on teeth) or rear sprocket (up on teeth) or both

&

2. choose whether to get a quick change sprocket carrier for rear or stay with fixed carrier & sprocket.

I'm sure the 748 boyz /gurlz will help you on sprocket options.

Go for it....I love having more accleration over ultimate top-end - which having said that how often (and where!) can you use it these days anyway.

wot he said - no point having 165mph top end if it takes a couple of miles to get there!

Knock it down 1 on the front (if its a 15 - DONT goto a 13 as it stresses the chain too much) or put 3 or 4 on the rear (this will require extra chain links, but they are putting a new chain on so no bother :D )

A stock 748s has a 14-tooth front sprocket and a 38-tooth rear sprocket, with a 94-link 520 chain.

A popular choice, that I recommend, for 7XX models is a 14-tooth front with a 41-tooth rear that will require a 96-link chain. The set-up will raise your ride height a little (4mm) which will improve the bike's cornering.

Cheers guys! Once again, quality advice comes forth.

I always understood the principles behind lowering the gearing, just wasn't sure whether it was that beneficial to actually do it.

Thanks again.
Jacko.
