Without losing that Gas Gas trial and off-road character, the new Trial SC is adapted to a level less demanding than that of the professionals.

This is for riders who are more interested in a leisure sports activity, or riding as a hobby, and are looking for pure fun in a day of trial. To do this we have simplified some components, such as the suspension, which are elements that are overlooked by riders who are not so expert in the question of adjustments and fine-tuning.

Gas Gas aims to satisfy the demand for fun from riders with this easy to ride and easy to maintain trial bike.

A Gas Gas bike made with high quality components but without the corresponding increase in cost.

A product adapted to the needs of an newer riders,  fans of a more relaxed, traditional style of trial, looking for a bike to enjoy getting out and about on at a lower price.

And although it seems like a contradiction in terms, the new Gas Gas Trial SC has come up with a magic formula for a bike that is both fun and relaxed without losing any of that authentic Gas Gas character.

How have we managed this? Firstly, with suspension adjustments and engine mapping pre-set for a mid-level rider and so avoiding the common pitfalls of attempting to adjust settings in the hands of the non-expert.

Secondly, by offering only one size of engine: a 125 cc two-stroke. An engine size that helps a rider get on well with the bike without unpleasant surprises for any riders regardless of ability. This is the same engine used in the RACING and GP, and still features the Keihin flat slide PWK28 carburettor.

And last but not least, an excellent geometry and balance with regard to mass distribution.

Both the front forks as well as the rear suspension of this model are slightly heavier than the rest of the series allowing better handling and traction in the new Gas Gas Trial SC on all sorts of terrain.
