You will need MS Excel 2003 or newer:

Here are a few pics of the DRZ version:

Its the same as the CRF version, just different gear ratios. Enjoy and be sure to put your current gearing and tire sizes in :thumbsup:
BTW - PM me if you find any inaccuracies on the sheet. I used a trusted internet site to get ratios, etc.., but they could be inaccurate.
Found this on ThumperTalk cause im trying to squeeze a little more top end out of my Xr600 SM so thought I'd share with you guys. You should be able to find the gear ratios in your manuals or Factory Service Manuals if you have one.
PS: Don't worry, there is NO malicious code or anything of that nature
