NR Bore Chain Saw Sprockets
After years of doing custom sprockets and adaptors to convert motorcycle engines into hot saws for racing we now offer a system that will reduce the cost of adapting a chainsaw sprocket to the motorcycle engine.
For many engines the DS0270 NR Hub Blank can be machined to fit the stock drive gear and welded on. We can also make the NR hub to fit directly on the crankshaft on request.

We will not be responsible for improper use of this product. Excessive chain speed, improper lubrication, misalignment, or tension of the chain may create a dangerous condition. Protection from the chain, and chips created by cutting near any persons is required for safe operation.
