SWAP KIT INCLUDES:
Bracket, spacers, bolts, chain roller, nylon elbow, block off plate, shift lever, speedo correction cable, radiator overflow bottle, radiator hoses, air filter, chain and rear sprocket.

Extra options include an additional 3D printed elbow that allows you to have the throttle body and air filter hidden upside the petrol tank which saves you the hassle of cutting your fairings to have the air filter sticking out the side. The No Cut Elbow is not needed to successfully do the engine swap, it just simply comes down to preference on whether you want the air filter to be visible or not. 

2021-2022 model Groms will need the frames top engine mount plate to be cut off, moved up slightly and then re-welded in place.
