It should do fine but my W650s did not have a sidecar on them so I really don't know. Easy to change the sprocket to get the gearing you want. Again remember this is an auction on Ebay and that $5499 is the starting price. I think usually people don't go to sell on Ebay auction until they have tried other ways of free selling like CL or here. I sold my W650s for about $3900 each and they were nice. Some people ask unrealistic prices for them.
