I did a search on this topic without results so I have to ask. Also, did I post this in the right list? Should I have gone to the racing list? I had a chance to talk to Henry Duga and asked about what's coming. One item he spoke of is the chain drive swingarm being developed for the 1125. What are the advantages of the chain drive swingarm? Is there weight saving? Durability? Or is it just convenient for changing sprockets? (Message edited by duggram on September 17, 2008) |

The advantage is just really just changing your gearing with ease which makes it good for track use when you want different ratios for different style tracks. other than that i don't see much advantage except that you can change a chain without removing much but a belt doesn't really need to be change nearly as often as a chain. |

Belt has many advantages over the Chain. Weight, Lash Free, Reduced maintenance, Cleaner operation, etc. The disadvantage is changing sprockets. |

Sounds like for a trackday rider belt is the way to go. Thanks for the replies. |

In the past, chains were more efficient at transferring power to the rear wheel with minimal losses. Buell claims the new kevlar belts have transfer efficiencies virtually identical to chains, but I haven't seen any independent testing on this. |

>>>belts have transfer efficiencies virtually identical to chains Actually, I think they are better. And . . . with a belt you've got ONE part, not 785. |

I seem to remember hearing that a BRAND NEW chain has less frictional losses than a brand new belt. After a few thousand miles, though, the belt hasn't changed but the chain now has significantly MORE frictional loss than the belt. At this year's MotoST in Daytona, an 1125r had a problem with rubber build-up on the rear pulley (likely from debris thrown up from the track) that caused the belt to creep off. At least, that's what I seem to remember hearing... If you race, use a chain. Otherwise... stick with the belt. |

I know when I was drag racing with my S1 in the AHDRA, I saw many a belt thrown. They look like a black snake on the track. Chain for drag racing, they hold the torque for the 6250 rpm dump and hold on's. Belt for stop light to stop light. Scott |
