Description


Tuning cylinders from the Italian tuning guru Max Quattrini for the "small" Vespa largeframe engines. The Quattrini is definitely the most powerful kit for the PX 125/150 engines. Already out of the box the 172cc cylinder makes a lot of steam.

Max Quattrini has "only" perfected the old and classic tuning recipe with large purge areas and low head angle. Despite surprisingly slow overcurrent and exhaust timing, the cylinder can make a lot of flow and convert it into a frightening amount of torque and power due to the large available exhaust and overcurrent windows.

The ingenious thing about this cylinder is its almost universal applicability.

The short control angles make the cylinder a good basis for a powerful touring engine even for inexperienced drivers. Equipped with a tame exhaust (e.g. BGM BigBox) and the carburetor of the PX200, the M1X cylinder is already a pleasure to use and offers a solid basis for a long-lasting engine due to the consistently superb material quality.

For professionals, the cylinder is also more than interesting. If the control angles are increased by mounting a long stroke crankshaft, not only the displacement increases but, and this is much more important, also the available flushing area. Since this is already very large in the M1X ex works, an extremely powerful cylinder is quickly created without a lot of effort.

If the outlet angle and the outlet window is enlarged with a large carburetor and a suitable exhaust the 30hp mark is reached quickly. Due to the tame head angles with 57mm stroke the cylinder can be used very well also with crankshafts with more than 62mm stroke without the need to lengthen the cylinder.

(Currently the performance record with 64mm stroke is 50HP measured at the rear wheel).

As it is appropriate in this performance class, the cylinder is made of aluminium and due to an ultra hard Nikasil coating very durable. Thanks to the 62 mm bore, you can get up to 172 cc of displacement with just 57 mm of stroke (hrs).

The M1X can be supplied with mixture via the standard rotary valve or optionally the housing can be converted to diaphragm. If you can't or don't want to mill your housing, but still want more power than the rotary valve inlet can provide, you should take a look at the M1XL cylinder. Here the diaphragm inlet is integrated directly into the cylinder.

The stable piston is equipped with two thin piston rings.

Conclusion: From powertourer to high-end racing engine, the Quattrini M1X can do it!

  • Recommended control angle on rotary vane: 132° from top dead center 63°n.OT.
  • Recommended squeezing dimension: 1.5mm (distance piston crown outside to cylinder head squeezing surface)
  • Ignition setting Variotronic: 22°f.OT. at 1500rpm
