If you wanted a comparison about power;
RC51 would have about 115-120 hp.
TLR about the same
VTR is 100-105.
ZX-12 is 160 or so, much more than anything else on the list.
Random thoughts:
TLR uses rotary damper instead of rear shock, which didn't work very well reportedly. I think Ohlins even tried their hand at making one for the bike and they couldn't even get it to work well. Compared to a "widowmaker" TLS the TLR makes a bit more power but weighs quite a bit more, the frame is much more rigid twin beam rather than aluminum lattice.
VTR uses the largest carbs ever fitted to a stock Honda motorcycle IIRC. Fuel injection was widely in use by '97, but Honda chose carbs for whatever reason. Miserable fuel mileage also, 30 mpg.
ZX-12 was rushed into production to compete with the Hayabusa, then neutered on the top end to limit top speed. 2002 saw a significant revamp that improved many complaints with the first two years models. Blue is a good color on these newer bikes, IMO.
