I have a 300 Raga rep, but I find it to tiring to ride for more than an hour at a time ( too old and too fat) so I am looking for a twinshock, which I think would suit me better. I noticed a 325 sherpa on ebay (4617232738). I dont know much about them so any advice would be helpfull, e.g. would that be suitable, Im 6`2 and 16 stone. Also is the price reasonable
