- Exhaust -RS Series 'JL Style'- lefthand- Vespa PX80, PX125, PX150 - 166cc, 177cc - Black
Painted black (heat-resistant) Lefthand design Precise turned parts on flange and manifold Broadband racing characteristics Suitable for wide tires Plug-and-play
The JL-Style Lefthand in black is a powerful racing system with a wide usable rev range. The typical two-stroke performance kick is already noticeable on the stock engine, but the exhaust shows its strengths particularly on setups from 177 cc. Historically designed for powerful 200cc setups, it also delivers a distinctly sporty performance on PX80/125/150 with 177cc cylinders and noticeably increases its power from around 5,000 rpm.
Compared to a box system, the JL-Style offers slightly less torque at the bottom, but compensates for this with free revving and powerful power build-up. The result: sporty propulsion in the mid-range as well as an increase in top speed via the revving capacity. The painted steel construction is robust, the look deliberately understated. The sound remains voluminous and throaty.
- Ideal with 177 cc touring and sports cylinders (e.g. BGM 177, Quattrini M1X, Pinasco/Stelvio 177).
- standard carburetor works, larger carburetors may make sense depending on the setup; clean jetting is mandatory.
- Demanding on small engines - with 177 cc the JL develops its full potential.
- Do not choose a primary that is too long so that the engine can rev freely.
Plug-and-play on the original mounting points in left-hand design. After installation, check and adjust carburetor tuning and ignition setting. Retighten screw connections after 50-100 km. For high revving setups, check the spark plug pattern and temperatures regularly.
✅ Exhaust body: steel, heat-resistant, painted black
✅ Silencer: painted black
✅ Precision turned parts on the exhaust flange and manifold connection - very high fitting accuracy and sealing capability
✅ Suitable for wide tires
✅ High-quality workmanship and durable appearance
High-quality, precisely manufactured turned parts are used on the outlet flange and manifold connection. These ensure an exact fit, high contact pressure and therefore a permanently tight connection. This reduces oil and exhaust mist, protects sealing surfaces and minimizes maintenance work, even with frequent disassembly.
