RPM Cycle in Dallas, short sleeved white and long sleeved black dealer Ts (the long sleeved black is a real neat shirt). Most knowledgeable Triumph shop for both old and new in the country.
Cycle Sport in Alexandria, VA, 2 Triumph polos (one green and one blue, no dealer name) before they took down the Triumph sign and went to strictly Yamaha (does that count?).
Martin Motorsport in Pottstown, PA, gave me a brown dealer T (and a helmet) when I bought the 03 TBA. Not many will do that anymore.
Mike Tingley’s in Missoula, Montana, short sleeved melton green T but he doesn’t do the shop name on clothing.
Performance Cycle in Bethany, OK (Oklahoma City), got a gray dealer T from them when they were just a small shop. They’ve moved west on 39th to a much larger building. Got the white with long black sleeves from the new location (XL that shrank badly and no dealer name).
