    I'm sure a handful of custom work on the rear wheel hub. I suspect they went to a non-cush drive since it's a race bike. Why not reach out to them direct?

    Front wheel is pretty straightforward, rear wheel is where it gets funky. The MotoBox guys machine the center of the wheel out and weld in an aluminum center with the Guzzi drive spline bolted to it. Less radical version is to machine the cushdrive 'fins' off a Guzzi Cush drive plate and bolt it to the Suzuki wheel after machining off the Suzuki cushdrive area. Unfortunately this leaves you with a wheel several mm off center (which is actually fine if you run a 150mm tire). By the time you do all this it's easier and not much more expensive to order Marvic or EPM wheels (if you can ever get Giovanni at Magni to reply to emails).

    What do you want in a wheel ?
    Cheap - Light - Strong
    Pick two... ;)

    Track day wheel adage ...
    Cheap - Light = Danger Will Robinson !
    Light - Strong = $$$$
    Cheap - Strong = Heavy

    To change to a more sporting wheel sizes, which the 18"-ers are not. I put 17"-ers on my Racer III with a sportbike 120/70-17 & 140/70-17 rear tri-compound radial tire set.

    Like Todd is saying, smaller diameter wheel, less mass spinning around at the edge,
    Ever lean out on a little park merry go round,

    Bridgestone, Metzeler, Continental all make fantastic 18" racing tires. From personal experience the Contis easily last 8 hours of use.

    Metzeler produces their softest compound (K1) in 18s.

    The Suzuki wheels are cheap, strong and light, that's why many top European vintage racing teams use them. Available in both 3.5 and 4.0 rears (130 and 150 tire widths)

    If you want to see how 18" tires perform Google Alf's Kawasaki Spa 2015. Mike Edwards does a 2.45 around Spa 110 18 front 150 18 rear.

    That's flying.

    Talking to a fellow vintage super bike racer yesterday he regrets going from 18" to 17" on his Z1. He feels the 18s perform just as well, give more ground clearance, are cheaper, last longer and offer more consistent performance. He is more than capable of winning races on 18s vs guys on 17s.

    Thanks for the input Andrew. It’s a really tough mental transition from race to street. I won races on machines that were laughed at when I first pulled into new track paddocks.
    Our friend Louis isn’t racing, and he has a 18” front, and a 17” rear. 110/80-18 & 130/80-17 is the only radial sizes available for the stock V7 rims. No lap times here, just strictly vanity in the end.
    So Louis, we can do whatever your wallet wants. I seriously say there is no gains to be had in going with made to fit 18” wheels in both ends over stock. The 17” Kineos we’re incredibly functional and getting super modern rubber on the V7 was flat out fun. Putting the Ohlins front end on was all the better, and now I can even offer dual front disks with the Kineos.

    The information I posted was directed at Harry who was asking about Suzuki wheels on a Guzzi racer here in the racing section of the forum.

    I tried finding an Asian rim to work on my LM3, none around, bought up by the guys vintage racing the models they came on. I used a modified swingarm and 1100 Sport wheels(no cush),machined off under hub to move wheel over. I had already put the Sport front forks on my bike. I still have to make a custom brake plate. 120/17 front & 160/18 rear.
