much as my 1200SE wire wheels look great, I can't help but wonder how the GRiSO might handle if it lost a bit of unsprung weight.

Anyone got real world experience with any of the (unbelievably expensive) aftermarket wheels out there?

And/or lighter rotors?

cheers

Most of the weight reduction for lighter wheels is directly from your wallet; but running them without tyres also removes a lot of the basic weight !

More seriously there are some weight saving data from Ghezzi here [You must be registered and logged in to see this link.]

Forget about lighter rotors, they will make a miniscule difference that even a MotoGP rider, wouldn't notice.
It is the centrifugal force of the rim and tyre that impacts the steering force, so unless you can get some unobtainable carbon fibre wheels you won't get a lot of benefit. There are some lightweight alloy wheels out there but the cost probably outweighs the likely benifits.

Getting a proper spring or shock, possibly front fork oil, and doing sag and rebound with your full gear on by a competent shop or friend will yield great results for handling...can make a night and day difference in handling.

Thanks PJPR, already took care of that with maxton suspension front and rear, feels great. Might just feel greater with less unsprung weight. Smile

Thumbs Up

Liked those PVMs enough to opt for a set for my bike here in California. With Covid and all manner of delays, it only took a year and a half to get them from Däs Mototec!

And yes, they sharpened up the steering and made the GRiSO feel livelier. It could also be that my wallet was lighter, so maybe that was also helping...

Thanks for the info

did you by any chance weigh them before you put them on the bike?

also, was it a straight swap with no hassles?

Sorry, but I did not have a scale handy to weigh them. All I can tell you is that my unscientific, "pick one up and then pick up the other," comparison indicated that the PVMs felt lighter. Thinking back, I would have appreciated having this information just to be able to calculate the difference between the factory spoked wheels and these.

Also, yes these bolted straight on to my GRiSO. They were also shipped with a custom disc brake adapter and a cover plate for the CARC rear bolt area.

One final observation is that the Guzzi factory must have used A LOT of Loctite on the rear disc brake bolts. I had to use a torch to break them loose.
