Inventory Quiz (MAMIQ), the KTM 125SX is best suited to a rider who: (1) Is new to the sport and wants to learn the ropes. A 125 teaches throttle control, clutch use, effective shifting and maintaining momentum. It is easier for a beginner to handle because it is lighter and less powerful. A quick survey of former AMA Pros reveals that they almost always start their youngsters out on 125cc two-strokes before letting them move to bigger and heavier bikes. Why? Because they want their kids to learn how to ride before moving them to more complicated machinery, and you learn faster and more thoroughly on a 125 than any other size bike. ( 2) Has been around the sport for a few years and has been burned out by the cost of 250cc four-strokes. Many 30-something riders return to 125cc two-strokes to reinvigorate their interest in motocross. However, once a rider gets to be about 40, the 125 two-stroke places too many demands on the rider. Additionally, really fast riders, like Pros and former Pros, aren’t good candidates for 125s. Their egos can’t take losing to a rider they could beat if they were on a big bike. Pros like to ride 125s for fun, but not if there is serious work to do. ( 3) Rides with total abandon. There is no strategy in garage with a couple hundred dollars worth of parts, the 250SXF four-stroke will quickly crack $1000 in parts and come with a big labor bill (for the mechanically inept).
