Looking for even more performance out of your 66/80cc 2-stroke bicycle engine? With the BBR Tuning Racing Series DIO Cylinder Body & Reed Assembly you’ll get the power and speed your build’s been looking for. A ported cylinder body with a high performance reed valve intake system, this race assembly was made for race engines in mind.
Unlike other cylinders, the BBR Tuning Racing Series DIO Cylinder Body is ported to allow maximum fuel and air mixing within your motor. The exhaust port can fit nearly any performance muffler as well as any stock exhaust muffler you want to run, which the intake port is specifically designed to accept the reed valve assembly included with this kit.
As we all know, reeds allow a bigger, better, and smoother flow of fuel and air in to your motor- and this reed doesn’t disappoint. Unlike other reeds that simply act as an over-sized manifold, this reed is made to accept only the highest performing carburetors around. With a 32mm opening, you’ll be able to fit hardcore racing carburetors like the BBR Tuning High Performance 2-Stroke OKO Style Carburetor without a single problem. With the right carburetor, this reed will deliver tons of fuel and air to your motor and give you higher speeds and even more torque.
With the BBR Tuning 21mm OKO High Performance Carburetor and Velocity Stack you’re guaranteed even more power and much better throttle response than any carburetor you’ve run on your motorized bike before! With its “D” slide technology and simple, effective jetting, air flow and fuel atomization increases for a smoother and faster ride.
The BBR Tuning Racing Series DIO Cylinder Body & Reed Assembly is a racer’s dream come true. Attach your stock parts to this assembly or upgrade to the recommended high performance head and expansion chamber, and get ready for a bike that’ll scream whenever you hit the gas
