Motorcycle and Scooter appreciation

GSXR6 vresus zxr400 - this is my opinion therefore am right, an it is gospel or godspell.

Of the two bikes the 4 is the better speced bike for suspension and brakes, both bikes IMO need suspension tweaking to fit the weight of the rider in full kit. The gixxer is a bit of a budget bike, parts wise. Think that the watercooled bikes shocks aren't rebuildable. All the 4 I've had were. Is the 6 much quicker that the 4? The 4 of that ear are really compact and have such mass centralisation that the handling is really good even with worn shocks. The mass centralisation thing was learn later if you look at a zx10 size compared to 4, the size is similar. Also I chose the Nissin brakes over tokico every day. I am a fan of suzukis, and a bit brand biased but the gsxr did have a certain buyer image that I thing that they will never shake. The 600 was the cheapy.

If I were going to make the jump, I'd go for the 750, higher VED bracket but similar wieght bike

If I was going to go for a bike that handled better than a 4 I would go for an early 600rr as the were the best handling bikes of the time.

Thanks very much for the honest thoughts.

My intention to move up the cc ladder is as I've mentioned before, to sell the ZXR 400 get a more modern and powerful bike with it hopefully not costing me much. My bike is an '89 and swapping it for a '99 model is very temping. It's interesting you say about the 750, but there is a part of me that likes the idea of moving up the cc ladder slowly mastering each platform first. I'm a Honda guy everyday of the week, but a good CBR 600 RR would cost me £3000(?) and that's out of my budget.

For reference

1989 ZXR 400 H1: 61HP / 163kg (dry)
1999 GSXR 600: 92HP / 174kg (dry)

Thanks again for all the opinions, really useful.
