Chain is the way to fly, been saying that for years. Best reason is as stated above. It can be easily fixed along the road. I have never had any other concern except getting it back to gether so I could ride the rest of the day. Had it fixed in a few min. and enjoyed the rest of the day. No need to ruin a good ride so you can run a belt.

Have to disassemble the drive shaft to change a tire on that bike?!?! My 64 BMW the whole drive shaft and differential stay in place and all you do if pull the axle and the wheel slides off it's splines. The rear fender is hinged so you can do it on the center stand. If you run a sidecar and carry a spare you can be back on the road in no time. The front and rear wheels are the same to boot. Gotta love those old BMWs.

I learned all I need to know about life by killing smart people and eating their brains.
