Pre 85
Did a lap on a PE Full Floater at Rockley and was impressed with the rear suspension, motor pulled strongly from the bottom too.
XR 200 is the 'Stealth Fighter' people scoff at them and they seem slow but you can get them moving quite easily. No good in deep sand or wide open sections.
KDX 200 pulls from the bottom better than the KDX 175
If I had to choose one it would be either 84 IT or KDX 200
Post 85
I test rode both the IT & KDX 200 in 86. KDX seemed the stronger motor so that's what I bought. Great bike and I have 2 of them neatly stored in boxes now
87 KX/KDX 125 was my next choice, great bike and I have an 88 neatly stored in boxes now.
