Fantastic superbike and great value. Three years ago after having a go on a friends 08 model I had to trade up to one. I went looking for zx10s and plumped for a mint C1 (thought 06/07 was ugly). How glad am I. It feels raw like a race bike, you can really feel the road, the air screams in the box and you're totally involved in the whole riding experience. Newer superbikes will get you round a race track tenths quicker, but you'll have so much more fun.
As journos have mentioned it does need respect, but only in the top half of the tacho. It's a great road bike and not restricted to the track. You can also ride it slowly as it's a real pussy cat. I'm 6'2" but still find it comfortable, can potter through town and have toured Europe only having a little discomfort on long motorway stints.
The bike has been 100% reliable the finish has surprised me, being really good and par with my Honda before.
It does like tyres and my mechanic says it's a pig to work on, but they are the only downsides.
Really struggled with what to replace it with but fate interferred and due to a neck injury I've now joined the sit up and beg brigade, getting a sensible Superduke! This is a great bike but I preferred my 10.
Go on, get yourself one, you won't regret it.
