GS1085 gearing

[gshub]

my Gs1085s is currently running 16/42 instead of stock 15/42 but it has a 130/90/17 rear wheel fitted ,stock S model has 18ins wheel in it.....
it pulls this gearing easerly even two up on a motorway it allways seem to want another gear...
so I have purchesed a 41tooth rear sprox and 16t front sprox anybody got any idea want the potential topspeed would be or will be to much...

1 tooth down on the rear wont make that much difference whereas 1 tooth up on the front would make a lot of difference

Yes m8..
but can you fit 17t front sprox with a 630 chain,wondering about clearance probs....

[Agemax]

you never mentioned what size chain you are running. either way a larger front sprocket should not have to much effect on clearance

Might be tight Steve - I can't picture it so you're going to have to measure your 16 and work it out - piD and all that.
