I must totally disagree with this. I had a Super Tigre 75 on my Tiger 60 and it was easy to start, the break-in process was no different than it was with any other engine, and it had plenty of power. It pulled that Tiger 60 around very nicely. My only complaint with the engine, at least this particular one, was that the muffler baffle plate kept coming loose. However, Super Tigre replaced the whole thing for me so I can't complain much about that.
