I think this bike is brilliant. I enjoy being a bit of a cheapskate/economiser, so it's the perfect balance of power with mpg. It's got enough pull to get you away at the front of the traffic light queues (this always bugged me on my 125!) yet is still amazingly economical - 77mpg! I have no idea how much more powerful a bigger bike is, but the step up to the Rebel 250 from my GN125 was phenomenal. Even if it's only 17bhp, I finally feel like I'm riding a real motorbike.
I suppose it would be nice if it could go that tiny, tiny, tiny bit faster on the motorway, but to be honest I don't care - it can hit 75 on a good day, and that's fast enough for me anyway. I'm a young rider but have no desire to go hurtling along at breakneck sportsbike speeds.
I had to replace the clutch about a week after I bought the bike, but I guess this is just down to the previous owner, or old age, or something. The bike makes a funny noise when the gears are engaged, but I've been assured this is nothing.
In general, great bike, I won't be changing to a new one anytime soon that's for sure. It's great on fuel and powerful enough to ride on any road, including the motorway, easily. Super easy to balance as well.
