There's an argument for the 6-speed tranny. Which isn't to say a 5-speed is trash and should be ignored.[...T]he FJR is now 15 years old, which makes it something of a senior citizen in motorcycle terms. So maybe we shouldn’t be surprised that it underwent major surgery. The biggest news is the addition of a sixth speed in the gearbox. That’s more complicated than it sounds, however, as to fit inside the existing engine cases the transmission had to be completely redesigned. Thus the gears are now helical instead of straight-cut, and rather than having dogs machined on the back of each gear there are separate dog gears in between. There’s a joke about dog years there somewhere…The engineers didn’t just add an extra gear, either. First and second were made taller, while fourth and fifth were made shorter; only the third gear ratio remains the same. Sixth is a very tall overdrive that Yamaha claims equates to a 10 percent reduction in rpm at cruising speeds.
A few people have retro-fitted the clutch to pre-16 models. Which suggests it has some value for even 5-speed versions.Also new is an Assist & Slipper clutch, which uses mechanical clamping force to help pull the plates together under acceleration and the opposite under decel. This allowed the previous single diaphragm spring to be replaced by three coil springs, which is said to reduce lever pull by 20 percent. Moreover, the Yamaha Chip Controlled Throttle (YCC-T) automatically raises the engine revs by some 200 rpm when the clutch lever is released at a standstill, easing engagement.
The real question, where do they have leftover 15As? Are there more beyond the one you're looking at?Hi everyone. I'm thinking about buying a new '15A. What is the opinion on the 5 speed vs 6 speed? Is the 6 better? I can get a good deal on a left over '15. No '19 s around here.
Are you currently riding a 2015A as shown on your profile? If yes and you would like to get the advantage of a 6th speed without buying a later model have the final drive modified with Star Venture internals. That will give you approximately the same gear ratio in 5th as the 6th speed. If you want to set it up for ultimate ratios, use a 190/55 rear tire. That will put the speedo dead on with gps.Hi everyone. I'm thinking about buying a new '15A. What is the opinion on the 5 speed vs 6 speed? Is the 6 better? I can get a good deal on a left over '15.
