I've not really posted a lot on the forum, but I have recently noticed a fair amount of first owners of the 675 and here is my first impressions. I rode a CBR600RR4 (on a 05 plate) and had 6500 of 99.99% of reliability riding and the only thing that ever stuck/jammed/broke was the rear brake light switch. Apart from that, brill bike. Anyway, the 675. First impression a very narrow bike and very light handling, but overall very happy. 300 miles in and after my first couple of decent rides (journeys of 70+ miles), here is my thoughts: 1. The rear brake locks the wheel a bit too easily for me. Is this a tyre issue rather than a brake??? Unsure!! 2. The heat shield is terrible for the underseat exhaust. 3. A bit thirsty, I got 70 miles for my tenner. Apart from the usual new bike tentative riding, my 300 miles have been great. However, a direct comparison between the CBR and the 675, I'd say so far the CBR is a better all round bike. After a couple of rides up to the Green Welly, this may change......... I'll just have to wait an see!!
