I'm now a ripe old 56 and slowing down. My current ride is an '08 300 XC. Prior to that I had a KLX450R and before that a KX500. I really love the 300 XC but it's just not the bike I want to ride. As much as I hate to admit it, the tractable 4 stroke power delivery was wonderful but the KLX was WAY top heavy. Actually, just too heavy all around. I've never really been a competition rider, just fast trails and hill climbs. One last item: At 5'8" and a short 29" inseam, I HATE TALL BIKES. I usually cut the seat foam, drop the clamps down the fork tubes and change links on the rear. My youngest son has a KX250F. It feels nice and nimble, certainly not over powered either. For most of my riding, the power level would be acceptable but as you may have noticed, I like big motors. I would consider a 450 but it would have to be very light. What I MUST HAVE is an electric start. I refuse to kick a 4 stroke. I've been looking around at Yammy WR250s, the Honda 250X, and KTM XCFs. Here are my hot buttons: -Light weight -Electric start 4 stroke -Carbs over FI (unless tuning the FI is dirt easy) -Street registerable is a plus but not mandatory That's all I can think of. What say yunz?
