F4i's are old tech. They have been making them since 2001. RR's have a much more aggressive seating position because its a Race Replica bike. F4's have a relaxed seating position and is more oriented as a daily street bike. RR is race tuned with more power.
it really depends on your riding style. If you like twisties, get the RR. If you like crusing around town, get an f4i. Also, you pay a premium with RR's. Parts are much more expensive. F4i's are more abundant and are cheaper bikes (like around 8 grand new compared to 9-10 for RR) Up to you.
Originally posted by JBaz if your new to bikes, you won't know the difference. The performance is much better on the RR, it can corner easier and a lot smoother than the F4. The F4 weights more as well.
Not really, check some reputable stats, you'll see 03-04 RR weighs more than F4-F4i. Just because it's new, doesn't mean it's lighter. RR achieves greater cornering prowess through other means. RR is also peakier, but it's a bit abrupt with EFI on 03-04 compared to F4i and F4 (carbs were still the smoothest during EFI's earlier stage). And then '05-06 600RR is significantly different from 03-04, I have no idea what the wet weight of 05-06 is, but I am guessing it's still around 430ish pounds. The F4s will have more usable midrange for street. Newer doesn't mean it's better every way, but it's better most ways for the track. Although it's one of those little nits most of us wouldn't notice, but when you're making a pitch, it's important to say in comparative context.
if you plan on going to the track on any regular basis then ya, get the RR. if not get the f4i espicially if u plan on riding almost everyday, still an aggressive bike, just slightly easier on on the body. oh and the one piece seat on the newer models is WAY better on the arse for both rider and passenger.
