Awesome purchase.
When I looked into it there isnt a huge difference between a SP1 and SP2, it's kinda like a GSXR600 K4 to a GSXR600 K5, Just a few refinements but because of the different name they sound like totally different bikes
Heres some info I came across:
Bigger throttle bodies, revised injectors and some engine tweaks give another 4 bhp.
The frame has been strengthened, with larger headstock, tougher engine mounts and the butchest swingarm ever, which is actually lighter than last year's to help shift more weight to the front of the bike. Honda reckon it'll turn a bit better than the old bike, although first track tests don't seem to confirm this - it's still a bit of a bugger to turn quickly in tight bends.
Back end feel is improved a bit and it seems the rider can now feel what the tyre is doing, and the revised injectors (now 12 port instead of 4) and mapping have improved the awful snatchy low-down power delivery.
Probably is the SP2 costs a lot more.
