Significantly more rev-happy than Polini Box Suitable for plug-in tuning No high exhaust angle necessary Plug-and-play Near-series box look Moderate volume
The LTH box for PX125 plays to its strengths on high-torque street and touring setups. It builds up speed primarily via revs, remains easy to ride at the bottom end and blends in unobtrusively with the standard trim. Ideal for engines that are not geared too long and therefore achieve both pulling power and a convincing top speed.
Compared to typical touring boxes, the LTH box revs noticeably further and more willingly - significantly more rev-happy than the Polini box, for example. This is achieved without extreme timing: The system works excellently with plugged cylinders and does not require a high exhaust angle. The result: a lively mid-range, free revving top end and a background noise level suitable for everyday use.
- Do not select a primary gear ratio that is too long, so that the engine can rev freely and generate top speed via the revving capacity.
Plug-and-play at the original mounting points. Ensure stress-free installation and tight connections. After installation, tune the carburetor properly (adjust the main jet accordingly) and check the spark plug pattern. Check screw connections after the first 50-100 km.
