Has any one weighed the stock belt and then the appropriate length chain? It seems like the OEM stock sprocket and belt would weigh less or the same as a sprocket and chain. But I haven't weighed them so I don't know. Maybe someone around here can enlighten me  |

The belt weighs less than the chain.
The front compensating sprocket weighs more than typical steel front sprocket.
The rear pulley weighs more than a typical Al sprocket and cush, and some steel sprockets.
The idle/tension wheel isn't light, and effectively doesn't exist on a chain drive.
As a system, the belt drive weighs more.
I can get out a pull scale and weigh all this stuff for actual numbers next time I'm pulling wheels on my bikes if it really matters, but this is what my shoulders and back tell me based on dozens and dozens of tire changes on both my Buell and Honda 600.
I personally prefer the belt drive over all and it's what is still on my race bike -- it's cleaner, quieter, the fixed rear axle makes wheels swaps easier, no adjusting for wear, no lube, etc -- but it's not lighter than a comparable chain drive system, in either unsprung weight or overall system weight. |

Thanks Jim. I totally forgot about the front sprocket and belt tensioner pulley. That would def make a weight difference for sure.
Like you I don't miss having a chain drive but there are definitely benefits to running them. |

I have a chain setup waiting to be installed, I'll try to remember to take some weights and report back. |

for street - the belt is outstanding
for track - yeah, I prefer chain |

Comparing drivetrain component to those of a 600cc bike is not quite fair. More HP and engine inertia requires beefier drivetrain.
I also, as is so often the case have trouble reconciling what JD claims concerning Buell wheels.
>>> Sprint, the OEM Buell wheels are not competitively light. At the time they came out, they were, especially the front, but improvements in Japanese wheels changed that. By 2008, front wheel and brake system weights were roughly the same, and the rear wheel is a good bit heavier.
Someone care to explain to me how a front wheel/brake system that is "roughly the same" (in truth still a couple pounds lighter) is not "competitively light"?
EBR has a new rear wheel that is class leading light, even in cast aluminum and that is compared to other manufacturers forged aluminum wheels. The front even more so.
It's too cool seeing an American sport bike leading the industry in such technological development. |

Next JD will be telling us how we won't be able to tell the difference anyway, so less unsprung weight is no big deal. But oddly he only raises that point when the fact of EBR's innovative lighter wheel systems is mentioned. He never mentions it when he is claiming (inaccurately) that other wheels are lighter. Odd. |

It's official. This thread now sucks. Twice. |
