Difference In Riding Between Montesa 315(2004) / Gasgas Txt 300 Raga (2005)?

Hello

my first bike was the Beta Rev 3 4-stroke who i'm now selling because i ridden a 2-stroke bike

and loved it more. Not so heavy as the 4-stroke and like the sound. I would like to know iff

somebody cann tell me the big difference in riding (track and between tracks for traveling in

the mountains) between a montesa 315 / 2004 and a gasgas txt 300 Raga / 2005.

I know the montesa has 5 gearings and the gasgas 6.

Thanks

Luc (the belgium rider)
