grasshopper Posted October 20, 2006 Report Share Posted October 20, 2006 What standard gearing should I have on my 07 250? The rear is currently a 42 and I'm not sure whether to fit the 10 or the 11 tooth front. My wife has a 125 - is 9/42 gearing right or should we go with 9/48? Also what chain is best for the optimum combination of lightness and weight? Thanks Quote Link to comment Share on other sites More sharing options...
essex rider Posted October 20, 2006 Report Share Posted October 20, 2006 Arent lightness and wieght the same thing?? The best chain is the iris one which is very lightweight and quite strong. As long as you look after it, it should last for ages. Quote Link to comment Share on other sites More sharing options...

grasshopper Posted October 20, 2006 Author Report Share Posted October 20, 2006 Sorry, I meant lightness and longlasting! Quote Link to comment Share on other sites More sharing options...
seandellear Posted October 20, 2006 Report Share Posted October 20, 2006 Hi I have an 06 gasser 125. On BigWiggs advice I changed the gearing to 9/48 and is spot on! Use second alot more but 1st for the bigger stuff! I would recomend this gearing 100%. Cheers sean Quote Link to comment Share on other sites More sharing options...
lewis_gasgas Posted October 22, 2006 Report Share Posted October 22, 2006 Id go for the Renthal chains last twice as long as any other and dont really stretch much quite a lot of the iris chains have been snapping around this area after a couple of rides...
