Aftermarket Wheels Question

[silas]

Lighter wheels seemed to make the biggest difference in handling. And then a lithium battery.
I've got a 6" back wheel on my '98 M900. They are forged aluminum Hi-Points.
Some 180 tires are wider than others- the Pilot GP 180 I have now is about 3/8" narrower overall than the 180 Pirelli Rosso Corso I previously had, the Pilot GP 180 is narrower and clears the chain a good bit more, it seems.

A new lithium battery is definitely on the to-do list.  I also found a used set of rearsets from Pinion [thank you for the install information!] and am working on them, hoping they shave a bit of weight off as well as improving my knee position. I got a garage heater to extend the season for my feeble wrenching skills before I put the duc away for the season. Between fitting the new wheels, new tires, rearsets and 2 other bits, not many miles on it this season but it should be ready to roll next spring. The bike came with a Barnett clutch and partial C.F. cover. I'm not sure if that saves any weight/rotational mass over OEM.

The original 3 spoke wheels on the older monsters are very soft.  Bent a few of them on Boston roads.  The newer 5 spoke versions or a machined forged after market set is definitely a step up in strength.  I just thought of the reduced rotating mass as an added bonus.

As for your clutch, check and see if the basket is steel or aluminum.

 By Barnett clutch, that could mean plates and/or basket. Barnett plate kits are very light kits and the baskets are lighter than steel oem baskets and similar in weight to oem alloy baskets. Light weight hubs, Ti bolts, Ti springs and alloy spring keepers are also available from various companies. A past weight loss crusade resulted in shedding over four pounds from theo clutch of an older M900. The flywheel had 2 pounds shaved off it, literally, which is a subject in itself.

Lithium batteries are a low cost weight reduction, but buy a high quality item like a Shorai to avoid problems.
