I just installed the Throttlemeister heavy bar end weights on my gen5. Nice difference. This is about the sixth or seventh pair I have used on different bikes. I got them for the VFR more for the throttle "lock", than the buzz control. I know the infamous V-4 is silky smooth, smoothest bike I have owned I think, but my hands got a bit numb at speed, these just about eliminated that. Especially when you can dangle your right arm for a couple of minutes when the time is right. Worked wonders on my 650 cc thumper. Costly but who cares, it's for the bike! Quality machining for the older two bolt Heli Bars. :thumb: :boobies3:
