I had a 748 SPS . . .
with an 853cc engine - what a tool!!!
The bike was fantastic and pulled like a train from just under 3000rpm right up to the red line - WELL WORTH THE MONEY in my opinion.
Mine had a 50mm Ti system and a JHP chip.
Had NO reliability issues at all.
Go for it - you will absolutely love it - I did!
