in fact a recent member here wrecked his FZ6R (XJ6 where he lives) and was given a loaner FZ6. he was immediately bitten by the FZ6 bug, abandoned his wrecked bike, and owns the FZ6 loaner! he finds it a considerable upgrade from the FZ6R, a bike he has rode thousands and thousands of miles. according to him the difference was significant, and noticed immediately
That was me, and yes this recap is almost spot on, I wasn't taken with it straight away because it required more finesse than the XJ-6 but after a week when I learned how to work with it I realised I didn't want my other one back! It's a great machine, much better gearbox for starters (even after six months I still kept knocking the XJ-6 out of gear, almost never happens with the FZ6), stiffer suspension is useful on corners, lighter weight makes low speed control that much more confidence inspiring... yeah overall it's just a much nicer package. You can cruise it around upright or grab some tank and high RPMs to have some fun, feels more stable and less hulking than the XJ-6 ever did, much as I liked that one.
As with most of the bigger Yamahas I've ridden, throttle response when rolling on from closed can be snatchy. Very easy to fix - be gentle for the first few percent as you open it and have the clutch squeezed in ever so slightly. This was the biggest change I had to make when coming from the XJ-6, it was like there was a "hump" in first gear when pulling away from a standing start where there was no torque and the Fazer felt jumpy/stuttery. Having the clutch in a tiny bit and leading with higher revs - less lazy, more racing style I guess - made pulling away from a stop that much smoother. That's what I mean about finesse; as she's more of a sports bike she needs more focused input from the rider, you gotta be careful with that change from 1st to 2nd as well, as with many Yamahas it's a bit clunky, you have to almost do a two step gear change with the clutch in to go 1st - through neutral - 2nd, requires a positive motion that isn't too gentle or too sudden either. Again, just a little more finesse.
The FZ6 isn't what I'd choose as a first big bike either, but then I bought a Thunderace which is an absolute beast and trust me, the Fazer is a lot more user friendly than that ever was! Just do some practice at both low and high speeds, don't push yourself too hard, and yeah make sure you've got good rubber. I took lots of recommendations from other riders here, on another forum, those I know in real life, those I meet in passing etc and they were spot on about Michelin Pilot Road 3s - as soon as these were on the bike and broken in the last remaining edge my old XJ-6 had was gone, I can do slow control on full steering lock now and never feel like I'm going to drop the bike, it's great for u-turns and weaves.
Yeah. Can't say enough good things about my FZ6 Fazer S2. It's a near-perfect 600cc sports tourer, I love it to bits.
