Ex NESC/NEMA novice/youth int racer here from the early 90s. I have not had a dirt bike in over a decade...sold my last bike (94 YZ125) in 1995 to buy a car. Have not ridden in 3 years (borrowed an 01 CR125 for a weekend) but a friend with a KTM 200SX (ex Dirt Rider test bike, actually) is bugging me to get back into it. Back around 2000, I borrowed a 97 KX125 with a full PC engine for a week, and went riding with a friend who had a 99 YZ125 at the time. The stock YZ was noticeably stronger than the admittedly ratty KX, but the KX ergos suited me better than the tall, stiff feeling YZ. My friend with the KTM insists that older bikes are just plain junk. This is only his 2nd bike - 1st being a ratty 94ish RM125, so I'm not sure he's the best resource on the matter. It's not like we'd be racing...just trail riding and some fun laps on a practice track. The last 3 bikes I owned were 91, 93, and 94 YZ125s...back when they were new. The 93 was my favorite as it had a super pipey motor with a noleen exhaust, ported 90 cylinder etc and other things I cant' remember. How archaic would an early 90s YZ125 be compared to recent bikes? Has suspension improved *that* much that a revalved early 90s model would still be junk by comparison for our intended uses? I know peak hp and power delivery has gotten much better, but is it a big deal if we aren't racing?
