Description
Polini adapted their successful For Race exhaust line to fit 50cc 2-stroke supermotards / off-road bikes: Polini Exhaust For Race high mount CE Beta RR. It's all in the name: the "For Race" is for racing in case you wondered...
The For Race for supermoto is a high-mount exhaust, as is typical for off-road bikes. Your bike will sound a lot more racy, and performance will be boosted throughout the entire rpm range. Revving up is much easier, the higher ranges are effectively boosted and you'll see higher top speed. The exhaust can be used with 50cc original as well as 50cc - 70cc tuned set-ups. Not recommended for high-end racing cylinders.
Best combined with a larger 19mm carburetor.
- high-mount, left side
- black aluminium silencer
- Sport / light tuning
- with CE marking
Polini For Race
The For Race series from Polini includes exhausts as well as crankshafts and clutches for scooters, 50cc supermotos and Vespas. Although the name sounds like ultra-high-quality and high-performance racing parts, this is not quite true.
The exhausts are not road-legal and are theoretically only intended for use on the race track, but due to their performance, which focuses mainly in the lower and medium RPM range, they are more suitable for sports / entry level tuning setups, which are appreciated for their balanced ratio of performance and reliability for everyday use.
The crankshafts are also suitable for sports cylinders, as are the few For Race clutches.
Polini fans looking for maximum power for the racetrack should therefore opt for the Evolution or even the P.R.E. series.
Exhaust scooter, moped, motorcycle
The exhaust has a major influence on the performance of scooters and mopeds. By replacing the original with a tuning exhaust, you can improve the gas flow and increase the engine power.
exhaust parts
- The headpipe or header is the connection between cylinder and exhaust, and an exhaust gasket provides the necessary seal. In street-legal systems, the headpipe is equipped with a legally required restriction. Some people remove this restrictor to increase power.
- The actual exhaust body or expansion chamber is connected to the header pipe. In a classic 2-stroke expansion chamber type exhaust, gas pressure waves are used to improve engine performance.
- At the end there us the silencer or muffler that discharges the exhaust gases and, with the help of damping wool, also reduces the noise generated by the vehicle.
Replacing the exhaust
For 2-stroke engines, various settings and components usually need to be adjusted when the original exhaust is replaced with a tuning version. These changes include:
- Adjusting the carburetor by replacing the main jet.
- Upgrading the clutch or replacing the clutch springs.
- For scooters, it may be necessary to reduce the weight of the variator weights.
Tuning Level: Sport
We categorize our products into different performance levels Original, Sport, Racing and High End , so that our customers can choose the right parts for their setup. It is really important to combine parts that belong to the same tuning level, this is especially true for cylinders, crankshafts and exhausts.
The products listed under Sport yield better performance than Original parts. They may have technical differences, such as the use of higher quality materials, a larger displacement or a performance-enhancing design. They are suitable for everyday use and have a long service life.
