I mostly ride city but would love to hop on an ride the interstate as well. My grom is all stock as of now and it just isn't fast enough for the interstate. Do you ever think it could be modified to run 70 mph? I want to stick with the same piston an cylinder for reliability. Im thinking I would have to go a tooth bigger on the front sprocket for more speed. The only problem is getting the hp to push it. Would a good intake, exhaust, ecu flash, fuel programmer get enough power? I think the grom would love a high compression piston if that wasn't enough power. What are your thoughts??
