The ’34 Roadstercycle® Trike uses a Fuel injected Yamaha V-Max engine. It has four separate pod type air filters sitting on top of stock V-max CV carbs modified into fuel injected throttle bodies. With a Nascar style exhaust the ’34 is an awesome machine, the wildest Roadstercycle ever built. Tons of power, great cornering, and just a blast to ride. It really gives it a sound all it's own.
