Description
SCR Corse Exhaust Handmade Cross 50cc / 70cc Derbi Senda / DRD clear coat (high mount), without silencer and with a clear coat.
It is made of steel plates (2 half-pipes welded together) and comes without a silencer. With quite a bit of increase in torque, it performs great in the mid and high rpm range. The SCR Corse Handmade Cross 50cc / 70cc Exhaust Derbi Senda / DRD (high mount) is definitely a racing exhaust (50cc + 70cc), but can also be used with 70cc sports kits. To get the most out of this exhaust, we recommend a 19mm carb.
Developed and designed for the race track, this SCR Corse Exhaust Handmade Cross clear-coat Derbi Senda / DRD (high mount) is NOT street-legal (no CE homologation).
YASUNI Cross HM
The Spanish brand was originally known in MotoGP, when two-strokes dominated the discipline. However, Yasuni has now also gained an excellent reputation for their exhausts for 50cc supermotos, which includes the Yasuni Cross HM.
The "Cross" exhaust from Yasuni is a high-mount exhaust. The ML is the racing version of the Cross.
PERFORMANCE YASUNI cross HM
The Yasuni Cross is powerful and high-torque, especially in the medium and high RPM range. It is primarily intended for 50cc to 70cc sport and racing cylinders.
To fully utilize the performance of the Yasuni Cross HM, we recommend using a 19 - 24mm carburetor and a reinforced clutch to prevent clutch slipping during off the line acceleration.
If you absolutely want a Yasuni exhaust, but have a setup with a very large displacement or very high power, you should opt for the low-mount tuning exhausts from Yasuni: Yasuni R2, R3, R4...
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
As a general rule, please check if the exhausts fits BEFORE REMOVING THE RESTRICTOR, otherwise the exhaust cannot be returned.
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: Racing
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.
Racing products are designed for a more extreme uses and are developed primarily for racing. Whether you stay at 50cc or increase the displacement, the corresponding Racing parts produce much higher performance than the original parts in order to achieve maximum power.
