I have been given the forms to join the Triumph Owners MCC, not sure if that is the same as the RAT pack
RATS and TOMCC are different. RATS is sponsored by the Hinckley factory for Hinckley Triumphs.
TOMCC (Triumph Owners) caters for all Triumphs, 1936 on.
Bevans RATS have members from all over Wales and even some from England. Check the website and you will see that ride outs cover all of Wales, England and beyond - some are weekends and even longer. I live almost as far away as you do but there are usually additional meeting points that would be closer to you depending on the run. This year include weekends in Devon, Bala, Much Wenlock, Cumbria, New Radnor, Brecon as well as a 10 day trip to Sardinia (fully booked)
