Ready to turn your regular ol’ bike into a full on moped? With the BBR Tuning 79cc The Beast Recoil Pull Start 4-Stroke Bicycle Engine Kit you get all the speed you love from a 2-stroke with all the power and durability you expect out of a 4-stroke engine.
One of the Most Powerful 4-Strokes on the Market
4-strokes are known for their torque but not their speed, but not anymore. This 79cc OHV engine will also keep you riding at speeds of up to 35 MPH, which is leaps and bounds faster than any other 4-stroke engine kit out there. That means you can take hills better than any 2-stroke can, and you’ll probably be doing it faster than they can, too.
Long Lasting and a Great Value
Let’s face it: sometimes we either ruin our engines from over-use because they just don’t give us what we want. You might have blown out 2-strokes running them up hills or spend hundreds trying to push that 4-stroke past its limits. It durable, cast iron cylinder can keep up with the wear and tear you give to it.
The centrifugal clutch eliminates the need to engage a clutch, and paired with its heavy duty transmission, fuel shut off, and ball bearing support shaft, this motor will be spinning like a top for a long time to come.
Compared to the cost of porting, polishing, and upgrading a 49cc 4-stroke to get close to the speed of this motor, the BBR Tuning 79cc The Beast Recoil Pull Start 4-Stroke Bicycle Engine Kit will have you riding the way you want to ride right out of the box
So when your ride’s just not cutting it anymore and you’re tired of spending all your money on repairing your motor, just strap this motor to your bike, pull the pull-start, and hit the throttle!
