STAGE6 CYLINDER StreetRace 50cc & 70cc
Top Performance
Both the 50cc and 70cc kit include a high-quality cast iron cylinder with five flow-optimised transfer ports and a generous oval exhaust topped by a high-compression (HC) cylinder head.
The engineers opted for a layout for excellent torque across the entire power band, which results in outstanding acceleration and allows for a much more dynamic driving style. Output and performance are well above the stock cylinder.
By the way, you don't need any high-end racing parts to unlock the full potential of the Stage6 Streetrace cylinders; a regular sports exhaust and a 17.5mm carburetor are absolutely sufficient.
The Streetrace cylinders are designed with a focus on strong performance, high reliability and a relaxed driving experience, so you can enjoy riding your two-wheeler every day in absolute peace of mind.
Low Profile
The prerequisite for relaxed driving in everyday life is a low-profile cylinder that conforms to road regulations. The Stage6 team aimed at developing a cylinder that stays in compliance with the applicable laws. Sound and appearance of the Stage6 cylinders correspond to standard specifications, so you can hop on your two-wheeler and take a ride without any worries.
Design and colours (black cylinder, silver-grey head) of the Streetrace kits are identical to the original cylinder, both the 50cc and the 70cc version carry the Stage6 logo and the marking 49 cm3.
Long Life
More power should ideally not lead to less reliability, which is always one of the main concerns every tuner has when upgrading their two-wheeler. The Stage6 engineers have taken a close look at this problem and designed a cylinder that provides optimum reliability, safety and durability.
The Stage6 StreetRace 50cc and 70cc cylinders are robust cast iron cylinders designed for everyday use with a reliable 2-ring piston; all materials and manufacturing quality of all components are beyond reproach.
The design of the Streetrace kits is based on the stock cylinder; the Stage6 engineers took on the strong points of the original cylinder and drew on their collective know-how, competence and passion to improve it.
To be able to guarantee that the Streetrace cylinders meet all requirements, Stage6 carried out a series of long-term tests under real-life conditions (outside temperature 35°, engine temperature 70°, exhaust temperature 705°) when developing the cylinders; despite intensive use, the surfaces of all components remained in top-notch condition.
