Hi there, I'm planning on purchasing a complete gs550 cafe racer this week. The bike looks stunning so I don't intend on rejecting this bike. I know it's not the type of fast I'm used too (ducati 749 and cbr 1100 previous bikes) however it's a beaut! My questions are: any possible direct engine swap such as gs 750 or 1100 or b12(bandit 1200)? Secondly, if not possible what other performance options do I have?
