The perfect supersport. Its not really a concept anymore is it? The 2007 Honda CBR 600RR and the 2007 Suzuki GSX-R 750 are both bikes I would put into that catagory. They are also the bikes im seriously looking at right now. After sampling both I have to say they are pretty similar. So let's nitpick. Price wise the 750 is about $700-1000 more. The 750 is obviously the more powerful of the two by about 10-15 rwhp. But you have to take into account the weight difference. The 600RR is 6-7 kilograms lighter (dry weights). Handling is pretty similar. They are both excellent. For someone of my current skill level it wouldn't make a difference. Gearboxes are both silky smooth. The underseat exhaust on the Honda looks nice but is hotter and heavier. The 750's low mount exhaust makes more sense (lower weight distribution, lighter). As a result you also get some storage space on the 750. The 600RR gets better mileage (18 litre tank vs. the 750's 16.5 litre tank) which gives it the slight advantage on those 500km days. Equipment-wise: the 750 has a slipper clutch and adjustable rearsets, the 600RR does not. Obviously i'd prefer them included as standard but aftermarket products are easy to come by. The 600RR has a fuel gauge, im not sure how accurate it is but I like it. Comfort wise they are pretty similair for me. Reliability/build quality/fit and finish: Both are excellent as should be expected these days. I do feel the Honda is just slightly better. For what I want to do (500km's or so a week in the hills and occasional commuting) they would both suit the purpose perfectly. If it comes down to price the Honda would win, its an excellent package, but is it worth paying an extra $700-1000 for a bit more power, slipper clutch and adjustable rearsets? This bike is not going to just sit in the garage, so after 20,000 km's+ which bike would be on top? What are your thoughts?
