The wheels are fairly heavy on these SOHCs. I am going to dirt bike hubs and rims. This is going to require a bit of time at my machinists shop, but I am hoping to shave close to 50lbs.
I doubt the wheels are that heavy. I recently weighed a stock K7 750, spoke front wheel, with a tire mounted, but no disk or axle: 24 pounds. I also weighed my Morris front wheel, with the tire: 25.5 pounds. (granted, Morris had the rep of being the lightest of the mag wheels at the time.) Have you weighed your wheels?
