February 10, 200818 yr Would be interested if anyone with the 08's have changed their gearing. If so what sprockets are you using.
February 11, 200818 yr Yes i have gear it down by putting a 10 tooth on the front instead of the 11. It makes it loads better.
February 11, 200818 yr Did Beta change the gearing between the 07 and 08? My 07 bike has perfect gearing (for me)
March 1, 200917 yr 09 300 4T with 11/42 sprocket combination - and finding that I'm using first for everything as second feels a touch too long after my rev3 where second was my favourite gear. As a gearing numpty, can someone tell me if a swap to a 10t front is the first / best option (rather than a different rear - whats the difference???) I don't want to screw up the current usability of first - rather make second a more viable alternative (considering the power available) Edited March 1, 200917 yr by Fivemeister
March 2, 200917 yr Author Since I could not find a 10 tooth countershaft sprocket either in Europe or here in the USA I had to keep the 11 tooth. The sprocket for the four stroke was changed from that used on the two strokes by providing an offset milled out area on the outside. Changing from an 11 tooth to a 10 tooth using the same rear sprocket (42) would result in an overall ratio of 4.20. I settled on the 11 and increased the rear sprocket to (44) for an overall gear ratio of 4.40. This turned out to be the perfect ratio for this bike.

According to the chart think you mean 4.00? So answering my own question - in order of difference - least to most 11/44 10/41 10/42? Edited March 2, 200917 yr by Fivemeister
March 3, 200917 yr Hi there As you will see from your chart, a reduction of 1 tooth on the front is roughly equivalent to an increase of 4 teeth on the rear. Before you proceed, consider costs ( a front sprocket is cheaper than a rear ) and bear in mind that a larger rear may mean adding links to the chain ( it is easier to shorten a chain ). Having said that it is best practice to fit a new chain with new sprockets anyway. Trialsoldtimer
