The Goped GSR40 is arguably the most reliable scooter to leave the production floor of Patmont Motor Werks. It is powered by the Zenoah G43L-D engine, a reliable, Japanese, four port two stroke engine. It was one of the first chain drive scooters to leave the Goped warehouse, but the simple chain drive transmission has yet to make a major change on more recent models.

Trevor Simpson Interceptor edition "GSR40TSi" Edit

Goped GSR40TSi

The TSi version of the GSR40

Due to the success of the Goped GSR40, Goped released a race inspired version designed to be a closed-course racer. On top of the GSR40 foundation, the Trevor Simpson Interceptor edition includes a dual steel fork, MX style bent handlebars and a ported (by Trevor Simpson) version of the G43L-D engine.

The GSR40 TSi edition was released as a limited edition package in August of 2002.[1]

TransmissionEdit

A centrifugal clutch with a chain drive provide transfer of the power from the engine to the rear wheel. A simple rubberized tensioner is designed to keep the chain riding correctly.

PerformanceEdit

The GSR40 was designed to be extremely fast and very exciting.

Controls Edit

One brake lever on the left hand side operating the front disk brake. One brake lever on the right hand side controlling the rear brake. One two finger throttle lever on the right hand side.

Brakes Edit

This scooter has front and rear disk brakes operated by bowden cable. The rear brake is plagued by its location in that it often becomes covered with dirt and oil thrown by the sprocket and chain. Regular cleaning will keep its stopping strong.

Throttle Edit

The throttle is operated by a simple finger lever pulling a bowden cable. The throttle can only be adjusted by the carburetor since there is no cable puller adjustment on the lever. This is common to all gas Goped scooters.

Adjustments Edit

The chain tensioner can be adjusted via a quick release bolt connecting it to the clutch housing. Because it is a quick release bolt, adjustments can be made easily on the road without tools.


ProductionEdit

ReliabilityEdit

The Goped GSR40 is an extremely reliable and simple scooter. Its design is robust and the G43L-D engine is reliable.

You'll never have to replaceEdit

If taken care of properly, you should never have to replace the Zenoah G43L-D engine. Under intended uses (cruising on road), the frame, wheels and controls can last the lifetime of the scooter.

You may eventually have to replaceEdit

Chain tensioner it will eventually wear out due to sliding interface with chain.

The #25 chain, pinion and sprocket will also wear out over time. Replacing the whole setup at the first sign of trouble is a good practice. Proper cleaning and maintenance can extend the life the the transmission.

The brake pads will eventually wear over time.

You should immediately replaceEdit

Nothing! The GSR40 is a solid scooter with a reliable engine.
