I used to have an XJR1300 and Street Triple. I part ex'd both for the Fazer 800 as I wanted a comfy sports tourer with some wind protection. I've had it 3 months and have done 4000 miles now. I'm very pleased with it.
It might not have the same grunt as the XJR as you would expect, but there is plenty. Acceleration is good enough for what I want.
I thought about getting the Fazer1000 but the 800 has a bigger fairing, and everyone I spoke to who had the 1000 said fuel consumption wasn't that good, a maximum of 130 miles till the light comes on. I get 45-55 mpg on mine. MCN dont mention the dip in torque at 5,000 rpm. Its quite noticable, and if you want to overtake quickly at lower speeds you need it at 6000. 5000 in 4th and it takes a while to pull through to 6000. I guess its all down to reducing emissions to pass the tests.
The can seems to get a lot of stick in reviews, but its not huge and doesn't look as bad as other cans you see these days. The Street Triple has 2 great lumps of metal next to the pillion seat.
There are some bungy points to tie luggage to. I wish the pillion grab handles were 2 inches longer at the back to tie straps to though.
The suspension is great on bumpy roads, I prefer to go the scenic routes so often the road surface is often less than perfect. Whacking the rear pre-load up helps to stop some of the initial soggyness. It would be nice to have fully adjustable suspension, but I probably wouldn't adjust it that far from what it is now for my riding. I dont do track days anymore.
The other bikes I considered were a Tiger or new CBF1000. I didn't like the service costs of the Triumph, valve checks every 12000 miles. Long term the Yamaha will work out cheaper, my local dealer 1.5 miles away are very reasonable, hence the higher value mark than you might think. Also the extras I got were well under RRP which helped. The new CBF looks a lot better than the older one, but still doesn't have the looks, and after talking to a friend it didn't sound sporty enough.
