Get the 03-05' GSX-R750 so I can ride it.
I had the choice to get any I4 1000 or 750-600 but didn't. The twin bug got me. Every thing I like about motorcycleing is expressed better in a twin. IMO. (Maybe a V4 or V5 :confused I dunno)
I do know that aside from the motor configuration my ZX-7R felt almost exactly like my RC. The biggest difference is the way they make their power such as the interval between power pulses. Not much would happen until the very last digits of the tachometer of the I4. It sounded like alot was going on but that wasn't the case. The wierd thing about it was, in terms of forward propultion you had to wring it pretty hard, and try not to miss a shift. However when leaned over The ZX-7R would quickly load up the rear an would be a handful at even moderate lean angles using a closely monitored throttle. With no warning. Sometimes I wouldn't even know I was spinning the rear. (spooky)
With the RC she just digs in and gives me an earlier warning when I'm about to exceed the rules of prudence or physics. I dunno maybe stock suspension has come a long way. I can only imagine what she'll be like with ohlins front and rear. Anyway That's one if the main reasons I went with the RC. That said I understand the RC isn't for everyone.
Between the 03' GSXR and the RC the dyno says they're similar in power (est.120-130hp, depending on who you ask) not doubt the GSXR will feel faster because it is a little bit but mostly because of the way it makes power. Peaky. I'll also go a little farther and say out the crate the GSXR is closer to race ready than the RC. So there's no way to go wrong between those two.
As for the TL.
The TLS had so much potential to bad it was wasted on the TLR. Honestly I would take a TLS over a TLR.
