1985 and 1986 are the lightest raceing fourwheeler ever made
Well some friends of mine were having a discussion the other day about what the true differences are between the first 2 years of the lt250r and the 87's and up. Well myself being the only person in the group who owns an lt250r 86 I was getting all the questions. Having never paid much attention to the other years, I don't really know what the differences were? Other then the T-bar seat and I think they added a powervalve system in 87. Any other facts or fiction would be appreciated......

Guys three are several distinct variations in the quadracer family. 85 -86, 87 - 90, 91 - 92.
Firstly engines. 85-86 engine is totally different to the 87 and up. 85-86 is case reed induction. 87 up is piston reed induction plus has the powervalve exhaust system. Nothing really interchangeable between the two engines at all.
87 Engine has an 8 petal reed valve, 88 to 92 has a 6 petal reed valve, 87 - 92 all other engine mechanicals basically the same.
The 87 and up engines have a lot more tuning potential than the 85 - 86, though these can still haul **** for rec riding for sure.
Interesting note, There is a 200 cc cylinder used in Suzuki's watercooled TS 200 trail bike which bolts straight onto I think the 85-86 bottom end ( I can check with the owner of this quad if anyyone is interested), these things will absolutely kill a modded blaster for 200cc class competition.
Chassis, several variations as mentioned. 91 to 92 by far the best with the totally revised rear end and adjustable damping on the front shocks.
85 has the straight seat, 86 went to the tee shape ??. quite a few chassis changes with the new engine in 87, different front shocks, longer with damping adjustments also, different rear shock, new swingarm / rear axle assembly. 91 -92 was the final refinement and the best of the breed with the revised rear suspension system (non floater).
