This is the kit we’ve all been waiting for! For a limited time and with very limited quantities we are pleased to offer these brand new, late version, Triumph 5-speed gearbox / transmission assemblies. Yes, we said brand new. We recently negotiated a great deal on these. No more trying to make worn parts function or putting up with chipped / worn teeth and dogs! For those of you with the appropriate skill set you’ll know that this assembly can be retro-fitted to both unit 650 engines and pre-unit 500 & 650 alike. Will also fit T150, T150V, A75, A75V, X75 triples but will need the 5-speed mainshaft for triples, PN# 57-4370.
Attention! These units must be installed by a knowledgeable, skilled technician!
