A few days ago, Japan's leading scooter magazine SCOOTER DAYS reported on our joint project. With that the story has become official and we want to give a brief overview here.

Taka from lambretta-magazine-japan.net will be responsible for implementing this. Along with MB Developments we will provide the parts for the project. Essentially, these are the complete bgm product range for the Lambretta.

Taka builds a demonstrator that he plans to put out for a test drive at Japanese meetings. Originally an Italian Series 2 was supposed to become the Rallymaster. Here the frame was unfortunately so ramshackle that it didn't fail because of it. Since a replacement was needed quickly, a SIL GP 200 officially imported to Japan is now being used. Special features of the GP 200 for the local market consisted primarily of the use of the SX steering head, a 4-way flashing system similar to the Jet models and a lying spare wheel.
Technically, the box should be brought up to date without losing its suitability for everyday use. The engine is trimmed with the Racetourkit from MB for the small block, the bgm crankshaft with 60 mm stroke and 110 mm Yamaha connecting rod, bgm 30 mm PWK carburetor and Clubman exhaust for a wide torque and low consumption. Hence the use of the MB membrane aspirator. BGM ignition and voltage regulators are used for the ultimate in reliability and versatility.
Chassis and brakes are also adapted to requirements. Gimmicks such as the navigation system at the DC output of the controller, rev counter, fuel gauge and one or two gimmicks round off the whole show.
After the terrible catastrophe, the decision was quickly made to auction the Lambretta for the benefit of the victims.

Finally they are ready, the Racetour cylinder kits from MB Developments!

This morning we received the first delivery of the Lambretta Race-Tour cylinder kits achieved. The complete Lambretta tuning kits are available for both the small and the large Lambretta engine blocks.

 

The standard sizes we have in stock are the 64 mm Bore with 190 cc and the 69 mm Bore with 220 cc. On request, we can also order the kit with the legendary 205 cc displacement (67 mm bore).

In principle, we also get any other borehole from MB Developments. For example with the forged race-tour pistons in: 64.5, 65, 68, 70 and 71mm diameter.

The kits are Made in the UK, and Mr. Bee has incorporated his more than 20 years of tuning experience into the development. An all-round carefree package has come out. The kits can be used with carburetors from 18 - 35 mm and all exhaust systems be driven.

The piston-controlled cylinders have the carburettor on the left-hand side, so they can be driven with the standard air filter box. The kits also offer the perfect starting point for every Group 4 racer.

MB has tested engines with Plug & Play built-in cylinders that put 20 bhp into the roller with 19 lbs ft of torque, perfect for fast road touring.

The kits contain the coated Race-Tour aluminum cylinder, the forged Race-Tour piston, a centered cylinder head, the MB cylinder stud set, seals, small parts and detailed instructions.

Mister Bee has sent us exclusive images of the prototypes of his new cylinders. There will be different versions for the small and the large engine block. First test bench runs resulted in Plug & Play 19 HP on the rear wheel with Devtour exhaust.
