RS125, the suspension feels the same. It's certainly not stiff like a race bike. I haven't thrashed the bike in corners and braked hard to test it yet. It handles and feels very similar to the Ninja 300 to me...light and nimble. Although the R3 is longer than the Ninja 300, due to the slightly shorter wheel base and perhaps other factors, it feels noticeably smaller when you are on it. The reach to the grips is not quite as far on the R3. I think the foot pegs are either more forward or lower, but in any case your knees aren't bent quite so much on the R3. The clutch pull on the R3 is harder than the Ninja 300 and brakes seem to engage better on the Ninja, but it might be you just need to apply the R3 brakes with a little more oomph. Mounting the R3 is a little harder. The seat is low, but the tail isn't so low, so you have to swing your right leg high to clear the pillion. That would only be an issue with short riders. When you move the R3 around by hand such as into and out of the garage, it feels a little top heavy, but I had the same feel with the Ninja 300 and other bikes. Weight feels the same as the Ninja 300. Gearing is definitely different. The Ninja 300 1st gear is only to get you off the line and is almost optional. Good thing there is a gear indicator on the R3 because it's harder to tell what gear you are in with not a lot of difference between 2nd, 3rd, and 4th. That may be due to the fact the transmission and engine is smooth and quiet and it's easy to rev up and down without the bike jerking from gear changes or engine braking. There isn't a clunk when you go into first gear or any other gear. I'm sure you could still lock up the rear wheel with aggressive downshifting though. Nothing stands out as bad on the bike. Fairings look good too. Photos are a little deceptive since the R3 is smaller and narrower than it might appear in photos. Maybe I'm dreaming, but I think I can feel the extra 25 cc. in all gears.
