Fubar as a vtwin Tuono owner I think the V4 seat is alot firmer than the V2twins seat. I've done 500 miles in a day on the T2win without major aches or pains, whereas a 20 mile test ride on a V4 tuono found my but starting to feel uncomfortable. How do you find it on longer runs? Saw the seat on a Kawi Versys thou - looked well plush
Bandito - most Ive done on the V4 is about 100 miles in one stint, and it did not feel bad, and way better than my last bike would have (Ducati 1198): but probably more down to the V4 having kinder ergonomics / riding position ??
But I reckon 500 miles on the V4 and I would need physio
