Yamaha’s 847cc triple currently resides in the production FZ-09, which we tested at the press launch a few months ago. We have just finished a longer term evaluation of the FZ-09, which we will post shortly. The engine in the FZ-09 is a gem … just an inexpensive air/fuel ratio adjustment away from perfection.
With word surfacing roughly a week ago that Yamaha has sought to trademark the “FJ-09″ name here in the United States, it appears likely that the new triple will next find a home in a sport tourer, as a smaller brother to the FJR1300. In our opinion, no significant engine tuning would be necessary … other than adding some additional flywheel weight to soften the power delivery.
