I have an '05 FJR and a '08 C14 with ABS. I've said it before but if I had to do it over again I'd be putting a 2nd FJR in the stable.
Not that there isnt anything terrible about the C14 but many of the posters here have touched on the issues that bother me. Maintenance (intervals and difficulty) as well as reliability.
My FJR now has close to 60k trouble free miles but the C14's seem to be running into a lot more issues. Yes, there are a lot of people out there with 30-40k+ miles but there seem to be a lot more issues or wider array of issues on the C14, than the FJR.
Warranty work depends on the dealer. I never really had any issues on my FJR so I cant speak to it but so far Kawi has sucked. I hope it is more delaer related than anything.
Touring- It's a toss up. I really do enjoy 6 gears on the C14, as you can be doing 85 at 4k rpm's and that nets you 70mph on my Gen1. The C14 engine and tranny is smoother but sure feel weak in the pants compared to my FJR. Much less torque, and you can feel it. Both needed Vstream windscreens to offer adequate protection for me. Ergonomics feel better on the C14 to me.
Handling- Depends on the rider. For me, even with 60k miles and the original rear shock, my FJR feels tighter and I can toss it around. Maybe its because I have more miles on it but both bikes have new PR2's and the C14 feels like it wanders sometimes.
I am 6' 180# and the C14 stock fit me great whereas I had to mod the bars on my Gen1 to get a more comfortable position. Heat? I dunno...it seemed like a big issue to Gen1 FJR owners but I never had an issue with it on mine and I havent really noticed it on the C14 either. It's truen about the seat height. Even at 6' with a 32" inseam my feet arent as planted squarely on the ground as they are with the FJR and lugging your legs over the bags requires you to do plenty of PX90 or Zoomba workouts to get the flexibility required to avoid scuffing your bags up with your boot heel.
C14- Premium Fuel
Gas mileage is also lower as I get 35-36mpg on the C14 vs 40-43 on the FJR day in and day out
C14- Valve intervals at 15k miles and those checks are a royal PITA. My FJR has proven very easy to work on over the years.
Only time will tell. I have 5k on the C14 so it's still young. The new C14's addressed many design/complaints present on mine such as the useless mirrors (WTF designed those anyway?!?!)
It's like I said on the C14 forum......it's like Ford and Chevy. Someone can show that the other is statistically more reliable than the other but owners on both sides have examples of piss poor reliability as well as those who have 1,000,000 mile cars. I think in the end my C14 will pile on some miles and perhaps endure a few more trips to the dealer than my FJR did but it's an enjoyable bike nonetheless.
