Unsprung weight- curious

Jay, do you know what the actual weight of you stock rims and the actual weight of the sun rims? Did you stay with the stock sizes? I was looking into swapping my rims for an aluminum set, but after some research it did not seem that the weight savings would be that significant (3 - 5 lbs). With the added weight of the dual disk and caliper set-up, it seemed to be a wash. If you can verify the actual weight savings, I may have to reconsider.

I've got the Excell rims on my bike, as well as the Lyndal rotors and an aluminum arm. The bike scales at 607lbs with a half tank of gas and the handling/stopping difference is dramatic...reducing unsprung weight is very expensive, though. Almost as much as some of the custom paint jobs seen here. Depends what you want out of your bike...
And before anyone says buy a crotch rocket; I've ridden BMW and Aprilia in the past year and they are lacking in the torque department compared to my HD. I'm happy with what I've got, but it is a major cash commitment.....

What other options do we have for lite wheels? I would perfer not to have Spoked wheels. I dont think that they would hold up to the riding I do (live on a dirt rode with big holes and have been know to run 80mph down it if I get pi**ed or late). I have been thinking of a Sport Bike / Buel front end.

I agree with CountryPunk on the spoke wheels being strong enough for bad roads and I know that motocross motorcycles are MUCH lighter than Harleys are, but in my owners manual there is a section on checking for CRACKS in the Mag rims by using a cotton ball and the thought is that a crack in the rim will hopefully catch a thread from the cotton ball and then you can inspect the crack closer after it has been revealed. I go to motorcycle races as often as I can and I have seen, first hand, a mag rim or two collapse in the middle of an AMA flat track race of 750cc Harley Sportsters. Not a pretty sight I’ll tell ya. Stainless Steal spokes are almost as maintenance free as you can get IMHO.

Joe, I have a call in to Buchanan to get the weight of the aluminum rims, but I haven't heard back from them. You might try yourself to get that from them. OEM weights were: Front rim 8 lbs, Rear Rim 13 lbs, Spokes 5 lbs/wheel. I kept my OEM hubs- the '06 spoked front wheel hub takes a dual brake set-up nicely. Howard Messner at Motorcyclemetal.com did it for me. I can tell you- the change in unsprung weight and handling was anything but a wash- If I couldn't afford the carbon fiber wheels from Howard, I'd go with the Sun rims. Jay
