Don't know how true this is,but I'm sure it will give all the kawi fans wood.


It's from a guy who works (worked) at Triumph in the UK, during development on their 600 engine.


"Most of the Triumph engines have been based on the Kawasaki units (certainly the 4 cylinder engines) as the Kawasaki’s tended to last the longest on the dynos at triumph.... when we did the TT600 the target engine durability was determined by taking all the 600 Supersport engines and running them flat out on dyno till they blew. The r6 engine lasted 35 minutes while the zx6r engine lasted 54 hours. Hence the triumph durability target became 55 hours.

The procedure was to break the engine in with some accels up to differing engine speeds with load. Then after an oil change and engine check to run the engine at Max power until the power dropped off significantly, stopping every 8 hours for an oil change and engine check (possibly service) then back up to speed again....

Yes, a second engine was purchased from Yamaha, and that one did not last much longer either. The GSXR engine lasted about 12 hours and the CBR was about 33 or something.

There was a reasonable spread of duration but the Kawasaki just seemed to hold within the 10% power margin for the longest......

The first R6 engine did actually go POP, put a rod through the side. the second engine just lost power."
