Ok thoughts so far on the Tracer,
The riding position is roomy and upright with great visibility. The bike itself is narrow and light with a riding position that is canted slightly forward. The bars are wide in comparison to the Fazer with loads of leverage which makes for a flickable, responsive ride. Certainly more manoeuvrable than the Fazer but what you gain in flick-ability... you lose in stability. The front paws at the air under hard acceleration and can feel remote in the wet (the first time I've had ABS kick in in any bike). That said, I changed the oe tyres on the Fazer at one point and it felt much more confidence inspiring. Of course. You can leave the TCS on, and use the mode buttons but unless it's torrential I don't bother.
So, the motor...... There was nothing wrong with the Fazer. Great linear power delivery that reacts well to being spun up and ridden hard. However, the Tracer is very, very easy to ride fast. The power is easily accessible and the motor spins-up quickly. You can leave it in third gear and it will cope with hairpins and any thing up to treble figures. However, the clutch is light and effortless and the motor has a split personality which also enjoys working the gear box and keeping things spinning.
The bike is quick, comfortable and well built. It's a lot of bike for the money but it does feel insubstantial at times. This probably because I'm still getting used to sitting upright and have never really ridden trail-style, light weight bikes. For me I'd like to be sat a little bit more over the front but that is just a personal preference.
In conclusion, I'm thrilled with the Tracer. However, at times I do miss the Fazer and on balance I'd say that these are two different bikes rather than one being better than the other.
