Hi

i have a 300 with 13/43 but i think the bike is too fast for classic race, what is better ..... 12/43 13/44 ???

My 240 is 10/44 .I find I only use 1st for real tight stuff ...

Back in the 80's most people put a smaller gearbox sprocket on. 13t is original, many went to 12t (as I did on the 300 Fantic I had in 1984)

I seem to recall 11t being used too.

I still have the standard gearing on the 300 Fantic that I now own, but I use the clutch a lot !!

today i tried 12/43, it's better

the only problem is the difference between 1° and 2° gear, like the 240, first gear is slow second gear is fast

the 305 has 1-2-3 more close but it's a 1989 bike

It's important to match your gearing to the sections you are riding in,When I set my gearing to ride the sections designed by the TY175 Yamaha guys first gear runs out so short it's only good for flat,tight sections,and second is still to high/fast,If I gear it a bit taller it first gear becomes much more usable,My clutch is a match for modern bikes so it can be used to negotiate the tighter sections and still have a longer pulling range for uphill runs.Running 11-44(I can't recall for sure the rear sprocket but that sounds right) I may swap on my SWM rear wheel and give even taller gearing a try,It's got a 39 tooth sprocket I think. Sorry,don't know the gearing on a 300 but the point is experiment until you find what works for you.
