Test-rode a 675 today. They only gave me a 15 minute ride, and had a guy leading me around on a Buell with a faulty gearbox, and the tyres were completely shot. Not the best start. Tipped it into a roundabout, rolled off the squared off middle of the tyres and the bike almost fell on its side. Basically the tyres were worn such that you either entered in fully committed, or pussy-footed around. There was no in-between. Somewhat surprising to me was that I was in no real discomfort at all. Felt completely relaxed and comfortable on the bike. Could feel it working the wrist a bit, but in a good way, such as it'd help my wrist to get stronger, as opposed to just causing pain. Ankle felt fine and worked well. Bike is amazingly narrow and feels very light compared to the old R1. Mid-range is phenomenal for a 675cc bike. You'd think you were on a litre bike the way it just grunts around. Even 6th gear at 60kph through traffic didn't cause it any bother. Where it's different is in the top-end rush. There isn't one. It's just a linear power delivery, yet (naturally) lacks the arm-socket ripping top-end power of a strong litre bike. This also makes it very deceptive. It'll get you to a high speed quite quickly without you realising it. Reminded me very much of a V2 in the way it does its job, and for me, that's a good thing. You can be lazy with it, or you can work it if you're so inclined. The air-box on the motor makes a fantastic growl when you wick it up a bit. Haven't heard anything like it outside of a Kawasaki, and for me that's important. I love that air-box growl sound. Light, smooth, grunty, comfortable, fast, lithe. I really enjoyed it. I asked them to call me back for another ride, this time heading up to Beaconsfield way to at least test it out on a few corners, and with tyres that are less shagged, and they might just have a buyer. I'll see what they come back with.
