I'm looking at adding a 00 M2 to my stable and was curious as to what the stock gear ratio is on this bike. What are they using number wise for the front and rear pulleys? What about the compensating and ring gear? The last Buell I was on IMO needed a six speed. I'll see if this bike will need one or not. With the six speed I can either add a little more low end grunt or go the opposite way and take some gear out via the primary or final drive gearing. Either way I can make up the difference with the six speed gear selection. Just building before I buy! I recently did this on my Bagger and it worked great. I lowered the primary gearing by going up on the compensating sprocket and than made up for it with the trans gearing. On paper I sure was confused but the guys at Baker set me straight and were spot on. | ||

This was saved in my own archive: I couldn`t find the original message. Some figures from UKBEG site on ratio's: The different combinations are: A = 29 TOOTH B = 55 TOOTH This is the "normal" UK spec and gives an overall gear ratio of 3.034. Top gear - 24.02 mph/l000 rpm giving a theoretical top speed of 163 mph at 6800 rpm. Fourth gear - 20.36 mph/1000 rpm - maximum speed 138 mph. Third gear - 16.80 mph/1000 rpm - maximum speed 114 mph. Second gear - 12.19 mph/l000 rpm - maximum speed 83 mph. First gear - 8.93 mph/1000 rpm - maximum speed 61 mph. At 80 mph in top gear the engine is running at 3300 rpm. A = 27 TOOTH B = 61 TOOTH This is the "full" US spec and gives an overall gear ratio of 3.615. Top gear - 20.16 mph/l000 rpm giving a theoretical top speed of 137 mph at 6800 rpm. Fourth gear - 17.08 mph/l000 rpm - maximum speed 116 mph. Third gear - 14.10 mph/1000 rpm - maximum speed 96 mph. Second gear - 10.23 mph/l000 rpm - maximum speed 70 mph. First gear - 7.49 mph/l000 rpm - maximum speed 51 mph. At 80 mph in top gear the engine is running at 4000 rpm. A = 27 TOOTH B = 55 TOOTH This is the US engine sprocket with the UK rear wheel sprocket to give an overall gear ratio of 3.259. Top gear - 22.36 mph/l000 rpm giving a theoretical top speed of 152 mph at 6800 rpm. Fourth gear - 18.95 mph/l000 rpm - maximum speed 129 mph. Third gear - 15.64 mph/1000 rpm - maximum speed 106 mph. Second gear - 11.35 mph/1000 rpm - maximum speed 77 mph. First gear - 8.31 mph/l000 rpm - maximum speed 57 mph. At 80 mph in top gear the engine is running at 3600 rpm. A = 29 TOOTH B = 61 TOOTH This is the UK engine sprocket with the US rear wheel sprocket to give an overall gear ratio of 3.366. Top gear - 21.66 mph/l000 rpm giving a theoretical top speed of 147 mph at 6800 rpm. Fourth gear - 18.36 mph/1000 rpm - maximum speed 125 mph. Third gear - 15.15 mph/l000 rpm - maximum speed 103 mph. Second gear - 11.00 mph/l000 rpm - maximum speed 75 mph. First gear - 8.05 mph/l000 rpm - maximum speed 55 mph. At 80 mph in top gear the engine is running at 3700 rpm. Hans | ||

Wow that is great information. That sure will alleviate a bunch of math. |
