Whoever edited the brochure did a lousy job ... I think it should read:
# 1 - R90 cross-spoke (not pictured)
# 2 - R83 5-star (Daytona)
# 3 - R86 star-spoke
# 4 - R84 X-lite (Monza)
# 5 - R81 7-hole (Imola)
# 6 - R87 double-spoke
# 7 - R82 8-spoke (Silverstone)
# 8 - R85 S-spoke (LeMans)
# 9 - R88 double-spoke
15" x 5.5" = R81, R82, R86, R87
16" x 6.6" = R83, R84, R88
17" x 7.0" = R85, R90
