Tested one when they first came out. Ideal commuter bike, nice handling, but it has it's limitations..........prefer the MT 03. Very little protection from the elements and a fair bit of vibration at the front end. Don't expect too much overtaking as it has a rev limiter that cuts in at about 5.5 K.
And yes...........it's half a Jazz engine.
Best to have a test ride yourself to make a comparison. The MT 03 is a far better bike (in my opinion).
