I'm very picky about saving weight, but these wheels are just so beautiful to my eye I don't care what they weigh..! I've got BSTs on my 996 and am sticking with those, but I need to buy another bike just so I can fit a set of these unbelievably gorgeous OZ wheels. I think they'd look really good on this..
Been doing some googling and found this interesting quote: “Remember, each ounce of weight reduction on the rim = 24 lbs @ 100 mph.” Wow!
I need a spare pair of wheels for track for my 2017 959 OZ Gass would suit if they fit the 959 How much?
I’m going to buy some gold. Tempted to ask @samieb what he wants for his, but the pikey in me lives a bit of gold.... I know what I can get the gass ones for new, so when ready drop me a line
Where have you heard that? That's a factor or 352 to 1 which seems high. I remember it being quoted in PBmag years ago as saving 1lb on the unsprung mass is equivalent of saving 6lb on the rest of the bike.
I’m guessing it’s a calculation based in the same: just extrapolating out over speed. 6lb at standstill vs 6lb travelling at 100 mph or whatever.
Fitted Marchesini forged today and compared to OEM cast wheels. 1.1kg weight saving on the front, but that was wheel and discs with used supercorsa to same set up plus a new s22, so maybe another 0.5kg of benefit in there if compared like for like, as obviously s22 is a heavier tyre and being new will also weighs more than a used tyre. OEM Rear with a worn supercorsa compared to forged Rear with new s22 was identical weight (11.1 kg) so perhaps a max of 0.5-1.0kg difference at the rear taking into account difference in tyre weights and tyre wear.
Update on this. Lovely unexpected tax bill of 5k has put a dent in my spending aspirations so Gass off the horizon. But, managed to pick up some forged S wheels (from a 1199 tri) for a good price. Get them gold coated and away The info on here helped me make that decision, cheers all
I posted this a while back if it helps, only relative values not absolute Swapped the wheels over today to get the bike MOTd later base model with OEM wheels and OEM disks 4.8mm thick, oem tyres Versus BST Rapidtek wheels, EBC disks, 5.2mm thick, Metzeler RR slicks weight saving 1kg rear wheel weight saving 2kg
