farmerj Posted October 20, 2013 Report Share Posted October 20, 2013 Hi, does anyone know what the Primary Drive ratio is for a TXT? I have an '01 321. Tried a search, but couldn't turn up anything. Thanks, Jeff Quote Link to comment Share on other sites More sharing options...
bilks Posted October 20, 2013 Report Share Posted October 20, 2013 (edited) Stock should be 11 front 41 which is 3.72/1 rear,optional normally 10 front most popular,it would be 4.10/1 Edited October 21, 2013 by bilks Quote Link to comment Share on other sites More sharing options...
dadof2 Posted October 20, 2013 Report Share Posted October 20, 2013 (edited) Take the primary drive cover off and count the teeth on the clutch and crank pinion At a guess it will be be around the 5 or 6 to 1 mark with the actual teeth numbers being prime Edited October 20, 2013 by dadof2 Quote Link to comment Share on other sites More sharing options...

sting32 Posted October 23, 2013 Report Share Posted October 23, 2013 what would you possibly be needing this information for? I have ridden all these years, never wanted to know the "drive ratio", ever, lol. Quote Link to comment Share on other sites More sharing options...
farmerj Posted October 24, 2013 Author Report Share Posted October 24, 2013 what would you possibly be needing this information for? I have ridden all these years, never wanted to know the "drive ratio", ever, lol. Great question! I have a Husaberg FX 450 with a close ratio transmission, and 1st gear is just too high for some of the riding I do. So I've been comparing final drive ratios with my other bikes, after running them all through the same trail/course. I thought I'd try to see what it would take to get the FX 1st to compare to 2nd or 3rd in the TXT...so I'm having fun with a spreadsheet and learning a lot about gearing!
