There are more mint Honda RC30s around today than a mint ZXR750 (H1 or H2)...

In my view the Honda RC30 was just an over priced bike because of its hand laid fairing and screen (back in 1989 the screen was something like $1500 on its own! and fairing well over $5000) and single sided swing arm... Yes it had massive support from Honda in racing so could afford the best riders and special engine bits.. but in show room standard.. the ZXR750 was better... and ZXR750 was just a street bike with a pillion seat!!!

My ZXR shown... and Lime green is faster!!!
