Having bought a track ready V4S and then spent $60k modifying it and trying just about everything you can try on them at track, if I were buying another liter bike right now it would be a V4R that I’d put the GP rear shock on, FKR 108 carts in the front forks, a Raceseats.It seat, a Brembro Corsa Corta 17RCS Brake MC, tank pads, and some slicks and have a very very good track bike.
That’s all ya need to have one of the fastest most capable bikes at the track.
And then because I have some expendable income and like the feeling of lightness the effectiveness of the Superlegerra wings I’d add those, some magnesium wheels, and Sicom rotors…but the rotors are on 10 month back order and counting.
