Description

MVT SC cylinder 70cc Peugeot 103 SPX / RCX

The MVT SC is without question one of the most powerful 70cc cylinders available for Peugeot 103 mopeds. Originally built for racing, this high-end kit is now available to everyone.

This is a brutal race cylinder for experienced tuners with the right budget and setup. Not for beginners or stock components. If your build is on point, you are getting a real beast - enjoy!

Note: Installing this kit requires solid technical knowledge, no plug and play.

Performance MVT SC racing cylinder

The cylinder has been uncompromisingly designed for power and speed - with optimized boosters, through-studs (as is usual with many tuning engines) and 8 large ports. Huge transfer ports and six intake ports ensure massive filling and gas flow.

The piston comes with a 12 mm pin and a 1 mm thick hard chrome steel ring. The high compression head is specifically designed to push performance even further.

This cylinder revs up to 10,000 - 11,000 rpm (with the appropriate setup). Port timings are extreme and clearly aimed at racing: 190° / 130°.

Setup recommendations for MVT SC cylinders

You definitely need a full race setup to run this cylinder properly. This includes a racing crankshaft, a larger carburetor (24mm), an MVT Digital Direct ignition and of course a performance exhaust.

The recommended squish clearance is 0.8mm.

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.

Aluminium cylinders

Aluminium cylinders are more powerful than cast iron cylinders, but require more regular maintenance and must be combined with different components such as a reinforced crankshaft and a larger carburetor.

How to run in an aluminium cylinder?

Aluminium cylinders should be run in for about 200 kilometers , and you should use a fully synthetic engine oil.

Note: To ensure optimum performance and reliability, it is advisable to measure the squish clearance. Just have a look at our tutorial How to adjust squish clearance.
