BBR Tuning V1 80/100cc 2-Stroke Motorized Bicycle Kit

Ready to start really burning rubber? The BBR Tuning 100cc Motorized Bicycle Engine Kit is one of the most powerful 2-Stroke motorized bicycle engines out there, outperforming even the most supped up 66/80cc motors in torque and top-end speed. If you’re looking for some major power without spending an arm and a leg on a pre-ported engine with all the bells and whistles, this engine kit is what you need.

1-Piece Cylinder

The 1-piece cylinder offers you more consistent, even torque than 2-piece cylinders. Coupled with a 50mm bore and high, these engines carry more weight, run cooler, start much easier, and keep your power output more consistent than other 2-stroke bike motors.

High-Performance Components

A high-performance engine is nothing with components to back them up. This kit comes with upgraded components to increase this engine’s longevity and performance, including…

• Yamaha-style high-performance CDI for more consistent spark.
• Super magneto for flawless starts every time.
• Speed carburetor for increased speed and torque.
• Pre-drilled ports in the clutch plate for smoother engaging/disengaging.
• Upgraded allen studs all around the engine make this a secure, long-lasting engine.

Balanced Crank

Unlike inferior 2-strokes with barely balanced cranks, this crank is balanced and paired with upgraded crank bearings. The stuffed crank case sits tight to the crank, which helps increase the compression of your motor.

** Please note: Sprocket Clamp Assemblies included with BBR Tuning 2-Stroke 48cc, 66/80cc, and 100cc, as well as 4-Stroke 49cc bike engine kits come with only 1x set of metal plates. Older production of these assemblies included 2x sets, but from testing and redesigning, existing engine kits and engine kits in the future will only require 1x set. This redesigned assembly helps secure your rear wheel sprocket better than in previous production.

On top of our strict quality assurance measures, we also back our engines with an industry leading 6 month warranty.

Product Dimensions and Specifications

The BBR Tuning 100cc bike engine kit is about 8.5″ height 7″ length 5″ width. The bike engine kit fits on standard, male frames with tubing of 25mm to 29mm in diameter. Larger frame sizes require drilling into bike frame with a stationary bolt and use the universal face plate to mount the front of the engine.

• 3 HP (horse power)
• 30-40 mph depending on the gear ratio and weight
• Fuel Economy: 100-150 miles per gallon
• Bore and Stroke: 50mm x 40mm
• Average Power: 1.8kw-1.9kw/8000r/min

The engine chain does not interfere with your current drive chain and peddling because it rides on the opposite side of the bike sprocket.

Disclosure of accurate engine size: While we have chosen to use the long standing factory branding engine size of “100cc”, the true displacement of the bicycle engine is 78.6cc. Down through the years China bicycle engine manufactures have advertised their biggest engine as 100cc, therefore we have listed them in the same way on our website. In the west, the volume of a cylinder is calculated by using the formula Volume = Pi x Radius Squared x Stroke. However,in the east the displacement of an engine includes the area of the cylinder head’s combustion chamber as well as the volume of the cylinder. Therein lies a discrepancy between measuring standards by the manufactures in China with those in the United States. However, all “100cc” engine kits on the market today are actually 78.6cc in displacement size if measuring by US standards.
