Hey ChrisD, i've got that Mag too! Feb 88 3&4 Wheel Action. Article: Superpower Confrontation. I also like how the article says that non of the editors felt comfortable on a 3 wheeler. My, how soon they forgot.
They had shoot out of true racers: Marty Hart's 86 ATC250R & 87 TRX250R vs. Sean Finley's 87 Tecate 4 vs. Jeff Watts' 87 Quadzilla.
From page 37, & I quote: "Without seeing our drag and lap time results, it was thought that the three-wheeler was the fastest vehicle in the bunch, and maybe it was. Too bad nobody in our group was able to expose it to it's full potential after spending so much time on four-wheelers lately." :shock: 
Marty also ran a -1 swingarm!
