Description

Cylinder kit Stage6 Big Racing 77cc Derbi Euro 3/4

Stage6 has dedicated itself to the development of high-performance tuning parts and is constantly taking on new challenges, which is why they are now also producing cylinders for 50cc supermotos. For Derbi Euro 3 / Euro 4: Stage6 Big Racing 77cc cylinder kit.

Design Big Racing cylinder for 50cc motorcycles

The cylinder was developed in close cooperation with the professionals from MXS Racing. On the one hand, it was possible to benefit from their experience in the field of manual transmission mopeds and, on the other hand, to use their own technical know-how, which enabled the Stage6 engineers to develop a thoroughly successful and innovative tuning cylinder.

Visually, the BigRacing keeps a low profile, but appearances can be deceiving. This is a true big bore aluminum cylinder – not just a bored-out standard version. It was designed from the ground up as a genuine big bore kit, featuring matched transfer ports and a large exhaust port that effectively supports the increased performance.

Advantages of Stage6 BigRacing cylinder

  • Simple installation: Installation is particularly straightforward as no milling work is required on the engine block. Squish clearance is optimized for the respective engine type.
  • High performance: 23 hp and 13 Nm were measured on the P4 test bench with a standard setup (24 mm carburetor, original ignition, racing exhaust).
  • Robust and reliable: The cylinder's port timings (190° - 125°), the large cooling volume and the high-quality Vertex piston ensure high reliability - provided that the setup and settings are right.

Use Stage6 BigRacing cylinder

Displacement is 77cc (50mm piston), i.e. not street legal. You should use a reinforced crankshaft with standard stroke.

From the outside, the cylinder is a replica of the original cylinder with a stamped 49cc mark; but don't worry, it is clearly a 77cc cylinder.

Note: we recommend using "long" cylinder head nuts to be able to tighten the head properly.

Without road approval.

Scope of delivery Stage6 Big Racing 77

  • 77cc aluminum cylinder, with 5 transfer ports and bridged exhaust
  • Vertex 1-ring piston, 50mm
  • High-compression cylinder head, one-piece, aluminum
  • Gasket set (base and head gaskets)

Note: Motorcycles with Derbi Euro 4 engines use a slightly smaller temperature sensor (thread: M12 x 1.5) than Euro 3 models (M14 x 1.5). To attach the smaller Euro 4 sensor to the cylinder head, you will thus need the adapter MF96.91010.

Notes and Safety

Stage6 BigRacing cylinder

The Big Racing cylinders are extremely powerful cylinders for 50cc supermotos. Although they are very powerful high-end cylinders, they offer a good balance of performance and reliability for intensive, regular, even daily use.

The aluminium cylinders have a displacement of 77 to 88 cc (with the corresponding crankshaft ) and were mainly developed for 50cc motorcycles with Derbi and AM6 engine, e.g. Rieju MRT, Beta RR or Sherco.

In combination with a suitable exhaust, a complete intake system and a suitable gearbox, the BigRacing can achieve maximum power with maximum torque and increased top speed.

The Stage6 R/T series delivers even more power, with uncompromising performance for use on the race track.

technical data :

  • Aluminium cylinder
  • 1-ring piston
  • Original big bore design (not simply opened up)
  • Transfer ports and compression designed for maximum reliability
  • 77cc displacement for crankshaft with original stroke
  • 86cc or 88cc cylinder for long stroke crankshaft
  • One-piece cylinder head
  • Discreet design with 49ccm lettering
  • Also available as a kit with exhaust or crankshaft
  • All spare parts available separately (pistons, gaskets)

How to Install a cylinder on a scooter, motorcycle or moped

The cylinder or cylinder kit is the heart of the engine on scooters, motorcycles and mopeds. It consists of a cylinder, a piston with piston ring(s), a cylinder head and gaskets needed for installation.

The service life of a cylinder depends on whether it has been fitted correctly.

Tuning Level: High End 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.

High End Racing products are exclusively designed for racing and should only be handled by tuning pros with the appropriate technical know-how. High-end racing parts often require modifications or machining of certain elements to accommodate the often larger components (larger crank webs, larger intake, etc.). Whether you stick with 50cc or increase the displacement, high-end racing parts offer much higher performance than the original parts and are the most powerful tuning parts.

Note: To ensure the reliability of the engine, it is important that the parts are compatible and that you do regular maintenance on your two-wheeler.

    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.

    One of the best
    This is one of the best cylinder kits if you don't want to go with a 100cc 2fast or something very high-end. My 2006 Derbi Senda flew on the back wheel with no help from the clutch in 1st, 2nd, and 3rd gear! I'm running it with a 21mm Karb and Voca racing crankshaft, and I get about 120 km/h top speed with 12/50 gearing.

    77 stage6 bigracing
    Mon 77 stage6 bigracing a au moins 10000 kilomètre avec le même cylindre, piston et segmentation, il est très important de laisser un bon temps de chauffe avant de jouer avec, personnellement j’ai mis un conteur de température koso et j’attend toujours d’être au moins à 40 degrés avant de tirer dedans, il faut aussi éviter de faire monter des personne derrière sois car personnellement mon piston a pris des coup de chaud quand j’ai fais monter des personne derrière et je tiens à préciser que je passe toujours mes rapport à saturation.

    Modification carter
    Est-ce- qu’il y a des modifications à faire au niveau des carter ou c’est plug & play comme écrit ? Parce que sur le pack avec le vilo ref : S6-7019310/PACK1 y’a marqué qu’il faut faire quelques fraisages simples du carter moteur donc j’suis un peu perdu mdrrr
