Gas Gas Pro 250
By TMX Archives on 18th Nov 10
The first of the adult bikes. Ive a confession to make here just before I tested the 2011 Raga a couple of months ago I was actually thinking of buying a 2010 model standard Gasser.
However, when I tested the 2011 Raga - with the new chassis - I just had to have one. So I bought a 250 - and finished the Scott Trial on it - so I do know this model pretty well.
The 250 is the default model for most customers and is as capable of looking after a raw Novice while at the same time being easily able to win a National trial with an Expert at the helm. If the watchword for the 125 is 'light' then the 250 has to be 'soft'. The power delivery is absolutely perfect for a trials bike being soft and forgiving, just building power with revs. There's no power step or peaky delivery, just lovely, useable power to cope with any situation.
The PRO chassis is now very planted and you can either ride just by steering or, if you want, hop the front (or back) end around a tight turn. Either is pretty easy to do. And you can tell the extra width in the mid-section over the previous models. It just helps with overall balance and stability. As with the 125 the suspension is set-up soft and lively without bouncing around all over the place. The exhaust note of the 250, as you would expect, is also soft and although the bigger engined models have more of a 'pop', it is controlled as the new exhaust system really delivers.
The Gas Gas six-speed box offers four ratios closely packed, all of which can be used in sections depending on what they are. There's then a jump to fifth for a cross-country ratio and another hop up to sixth for roadwork. On the 250 it doesn't really matter too much if you are a ratio too high or low in a section, chances are that the forgiving motor will alow you to easily get away with it.
The 250 has always been the model of choice and if anything the 2011 ofering simply reinforces that view. Great bike.
