While researching a little info on gear ratios, I came across this great tool for any changes you may think to do to your bike.
Change the parameters to any changes you may plan on your trx and compare the results in the LEAD diagram and you can change things from rider and bike weights, tyre size ,gearing and outputs.
You have 4 graphs to compare info on, but the lead graph gives you a 0 point which is with std specs and + and - when changes are made.
You can load multiple changes in there if gearing and rider and bike weight changes, torque and horespower outputs
Love that when I put in a conservative predicted specs (torque,HP, bike weight,and tyre size) on my rebuild and find a 37metres + gain at 10 seconds using stock gearings and rider weights as a common.
shame I can't change gearbox ratios.
But there is a tdm900 in the menu also to compare to.
Shame ..no yzf750 in there .
1st 3 gears are the same as yzf750/tdm900 and 4th in the tdm900 the same as 5th in a yzf750 and 6th matching 5th in a tdm900
So you can see the yzf750 box being a little closer ratios with 4th gear being not as big of step than the tdm900.
I would not be suprised if 4th ,5th and 6th from a yzf will fit straight into a tdm box..
yzf750 std...16/43 sprockets and tdm900 16/42
