I would like to swap swing arms from chain drive on my 1190SX to the belt drive from my Buell 1125R. Has anyone done this, can it be done. My 1125R is my "track bike" and the SX my street bike so I am not concerned about loss of power etc. on the EBR by going to the belt drive. My only concern would be the belt drive, breaking belts, but even though the power is up on the EBR it shouldn't be enough to tear up the belts, I hope. Just hoping it is easy to do. | ||

The belt is more efficient. Whether it will handle the power level of the 1190 is a different story and I don't have an answer for you there but it is more efficient. | ||

From what's been posted here, you will also have to swap rear wheels. Belt sprocket won't fit on the 1190 wheel. | ||

Hugh is correct. You will have to swap wheels and tensioners as well. | ||

Does the swingarm need to be changed? On my RX there's an insert that looks like you could get a belt through. It's not the same length as the 1125 swingarm? | ||

The belt is more efficient. I'm no engineer, but this is exactly the opposite of everything I've ever heard, read, and seen. I've seen dyno comparisons of the same motorcycle with the exact same final drive gearing with both belt and chain drive installed. When chain driven, the bike showed 3-4 more hp, indicating less driveline loss. What the belt most certainly is would be less maintenance, lighter in weight, and quieter operation. | ||

A belt will absorb more energy than the chain will. Despite it's many moving parts the chain still provides a more efficient transfer of energy, but not enough to make a big deal out of. The upside of a belt is maintenance at the cost of versatility. It's not as simple to change gearing with a belt. I am on the hunt for these parts myself. To do the swap you will need, 1190 primary drive sprocket & mounting hardware. The spacing is different between 1190 & 1125. 1190 rearsets & compatible exhaust Ebr swingarm Ebr tensioner Ebr chain guides Ebr wheel Ebr final drive All in all well more expensive than it is worth. Also, I do not know if the 1190 shares the same offset as the 1125 does from the COG. I'm betting it doesn't. So even if you do do it, it possibly will be no more than a conversation piece or a coffee fetcher. My advice? Forget it and search out an ex racer looking to return to belt drive on their 1125. If you're creative, fab your own setup. | ||

Since I own the Buell 1125R and the EBR 1190SX, I'm hoping it's a matter of swapping the parts (wheels,rims,drives,swingarm, etc.)and or adding any special machined spacers etc. If someone has done it and had input would be helpful. I'm NOT concerned about power transfer etc. I just like the idea of less maintenance for the belt drive to use it on my EBR, simple as that. | ||

Ah I see. So your primary motive is the belt on the ebr not the chain on the 1125. There is a guy who snagged the necessary parts from an 1190 for his cr. I'm not sure if he has gone through with it yet or not. I'm sure he will post when/if he does. My bad, I had mistaken your motives. Then you already have all you need, it should be simple as swapping the parts. Just measure the horizontal spacing of the rear wheel from the frame to verify offset.Then youre golden. I'm curious to see how the belt holds up. | ||

If you decide to part with the rx chain parts and wheels I'll gladly take them off your hands! | ||

You'll want the non-adjustable swingarm with the belt so you don't have to worry about setting belt tension IMO. Plus I don't know if the spacing is the same on the RX and 1125 swingarms. | ||

Rick, actually I plan on swapping the two drives, wheels, rims, drive systems. I will put the chain drive, swing arm, rear wheel etc. from the 1190SX onto the 1125R. I then plan on putting the belt drive system,(swing arm, wheel, rim etc.)onto the 1190SX. I was hoping that someone has done one and or the other and could offer advise on problems or additional things to consider, ec.. | ||

Did you ever do this swap? from chain to belt? |
