Over the past 6 months I've built this Razor SX500 into a bad ass pit bike that does over 60mph. It was electric beforehand from the factory. The batteries at electric motor went out and I found a 3 horsepower Briggs & Stratton engine. I ended up putting that motor onto to the bike and it did 45 miles an hour. The motor threw a rod through the block and I put a 110cc engine on it after. It's still running strong to this day. Enjoy!!
