TUNING SPORT – high-performance
For race use only. Not admitted in the area of the German StVZO! Product description
A perfectly balanced and designed race exhaust for motors tuned for everyday use and rallying.
Where a four-stroke motor requires valves, camshaft, exhaust and a turbo, a two-stroke just requires a well designed exhaust. A few pieces of sheet-metal modelled to create a form that harmonises perfectly with the layout and size of the openings in the cylinders bore, known as transfer and exhaust ports. The design of the resonance chamber not only influences the removal of hot exhaust gases, but the pulse effect also affects the flow of fresh fuel mixture into the cylinder. On modern two-strokes this technology is the main reason for its superiority over the four-stroke motor.
As simple as the description may seem, the creation of a properly formed expansion chamber body is a science for itself. This is where the wheat is separated from the chaff. Really good exhaust fabricators are as rare as uncooked steak and often only maintain limited production runs, making their products usually expensive.
NORDSPEED, based near Bremen in northern Germany, enjoy an almost legendary reputation as far as the production of excellent race exhausts for vintage geared Vespa and Lambretta scooters is concerned.
The systems created by Tobi Russ
ann for the 200cc Vespa largeframe models represent an absolute benchmark in the world of exhaust manufacture. The limited space between the cylinder studs that leave the transfer ports with a restricted amount of air to breathe is his area of speciality and the design of his exhausts makes the best out of this unusual motor layout.
and NORDSPEED have combined their efforts in this field and the result are exhaust systems with the most powerful design, coupled with modern features such as EGT and a lambda sensor connection possibility.
Technical specifications of all by NORDSPEED exhaust systems:

Double flange, suitable for TS1 and original outlets.

EGT connector.

Lambda/AF sensor connector.

Flange plate allows the attachment of most common silencers.
Touring :
The Touring produces ample torque to provide an agreeable power-band delivery combined with a reliably predictive performance all the way to its impressive maximum power output. Whether cruising round town, on an urban commute or even on long motorway trips, the Touring remains unbeatable thanks to its dependable power characteristic and generous torque values. Its high performance and torque output represent a benchmark reference in road and sport orientated tuning for Lambretta scooters.
The Roadmaster shows its true potential when combined with the suitable peripheral components and porting. This involves a larger carburettor, a reed valve inlet port and a tuning cylinder with adequate transfer ports.
To fully exploit its advantages the Touring requires matching with a cylinder possessing suitable port timings
– Transfer port timing : 124
-130

– Exhaust port timing : 184
-192

– Blow down timing: 29
-31

Conclusion :
The perfect exhaust to complement a very strong road-going motor set up, complete with a wide power-band and a balanced combination of strong torque and high power.
SIP- TIP : A well set up carburettor and ignition are essential for a reliable motor. Tools such as a strobe lamp (#FS118600) and a degree disc (#83002000) are available in the shop. The jets for the carburettor set up should be from the same reputable manufacturer, as numerous producers work with different manufacturing tolerances. We recommend the purchase of a jetting kit from either or KMT.
