I'm about to buy a 100 Enduro (Berkshire?) from a "friend". I plan to register it & use it around town & for some dirt riding. I thumbed thru the Penton Manual, HP is something like 16, it suggests a trans oil change after every long enduro. Is this bike geared toward competition? (Sachs Mtr.) I realize the suspention is a bit "short" on travel, but will the cycle hold together OK for my 215 LBS.? (Occasional light trail usage.) Lastly: about what is the range in price that this bike, with lighting, 2.5K, Speedo, Orig. Tool Kit, could bring? Thanks
