Now bear in mind this was my first go on an MX bike ever so some of the comments may not hold true if I was riding the bike flat out. (I didn't go WTO, they weren't my bikes and I didn't want to crash 'em or me!)
I went on the CRF first and felt instantly at home. The power was silky smooth and there was loads of it, not nearly as intimidating as I thought it'd be. I've had a KTM LC4 Supermoto so everything seemed that little bit more familiar. Being a four banger the bike went like sh*t of a shovel without ever really feeling like it was trying. Handling, well I'm not too sure, as I said I didn't go flat out and the bike was never out of shape, I got a bit more confidence coming out of the corners and sliding the bike around. Top Notch.
Then onto the CR. I got on it after the CRF and rode round the same little track. The CR *seemed* a hell of a lot faster than the CRF, I think this was because of the sound, the CRF never sounded stressed where as the CR seemed like it was just baiting you to go 'faster if you dare', and you had to oblige. :) (Saying that, the gearing also seemed a bit shorter on the CR.) The CR was a totally different ride to the CRF, the throttle was more like an on/off switch, the CRF you could wind on through the turns a bit better. Handling wise the bikes were similar although the CR seemed more snappy than the CRF, partly due to the on/off throttle action. I always got the impression the CR would be the bike more likely to spit me off.
My first question was shall I get a 125 or 250? I'm quite happy on the 250/450, they're nowhere near as lethal as I originally thought, they can both be ridden slowly, IF you want to, which was my worry. :)
The only thing I'm not sure about is how the bikes will perform once I can ride mx a bit better. Does the fact I feel at home on the CRF mean I'm riding it too much like a road bike or just that it fits me better? I dunno but I'm going shopping today. :)
