What a load of c**p that statement is, people buy the bigger bikes because these bikes are put in the market place.
All that power only suits a very small percentage of riders, people think they need it and thats the problem
The 250 Beta, the 250 Gas Gas, 250 Sherco would suit 90% of riders, the big hill climb you are talking about crops up once in a blue moon, if you struggle to get up this one section and ride the rest better on a much softer more controlable bike then I suggest that this option for a lot of riders is better.
I convinced a friend of mine, who is fairly useful at national level who has had 270 Beta's for a few years now to go for a 250 in 2006, he has just bought a 250 2007 model
The beta 4 banger 250, like the Mont 4RT will be and is enough for most riders...............
Steady Tiger ......if your in Kent, Sussex or Surrey pop along to a trial and see how many 250's there are.
