Aye fairly easy to fit, the only difficulty as such is the mapping. But even then there's a fair few places around the country that have all of the pre-set maps :)
done it to a gixxer thou wasn't that hard to fit hardest part was to get the maps sorted so we took it to a shop to get maped.
guessing its for the busa? youll need the PC5 to make the busa full power and get a quick shifter wile your at it a good party trick thats worth it XD
Up here for thinking, down there for dancing Toy, ordered the PC5 today, cost me £390.00, not gone for the quick shifter mind. Btw Busa is full power to start with, it's the later ones which were restricted.
Depends on the bike really, my brother put one in his CBR1000 and it took a few hours to get down the to injector wiring and throttle sensor etc. Suppose some bike will be easier, just with his everything under the tank was a tight fit.
Other than dismantling half the bike, pretty easy to install. Just time consuming
