Poor weather affected the 80th anniversarytt in 1987 and the Production A and C classes, due to be held on Friday, the final race day of the week, were moved to the Saturday. Although the Senior took place, albeit cut to four laps, the weather was too foul for the Production races to take place and they were cancelled. It was the first time ATT race was completely abandoned. The new Fzr1000yamaha had topped the practice leaderboard in the hands of Johnson and Dave Leach but it looked like it would be a close race between them, Johnson’s Loctiteyamaha team-mate Nation and the GSXR1000 Suzukis of Wilson, Mellor, Glenn Williams and Rob Haynes.the CBR600 Honda had dominated practice week in the C class but it was all to no avail. Johnson’s moment of glory had come earlier in the week in the three-lap Production B race but only after Nation had run out of fuel. Aided by a new lap record of 111.64mph, he was leading by an impressive 24-seconds when the tank ran dry just three miles from the finish but what was left enabled him to limp home in third. That enabled Johnson, who was rapidly getting the tag of ‘Mr Production’ to take his third win in four years but it was tight as new star Morrison was only 4.6s adrift at the chequered flag on his GSXR750 Suzuki.the consistent Wilson took fourth. At the same time, the D class was taking place and the FZR four-stroke 400ccyamaha proved more than a match for the 250cc two-strokes, with Woodland making it a great day for Loctiteyamaha with the victory and Wheeler taking second on a similar machine, although he was almost a minute behind. A brave ride by Oxley on histzr250 Yamaha saw him take third, just a second behind Wheeler, with Cannell in fourth and a thirdtzr in fifth in the hands of a certain Steve Hislop.
