Triumph Trident & BSA Rocket III Parts
I like to think that Triumph and BSA triples are the “forgotten ones” due to the fact that everyone is focused on owning and restoring the popular Triumph and BSA 650 twins these days
Both Triumph and BSA three-cylinder machines broke the news when they first arrived here in the states back in 1968, not to mention the magazine headlines and records archived both on and off the race track
With the Triumph and BSA three-cylinder models gaining traction and popularity here in the states Honda then came out with the “CB750” or known as the “Honda Four” which was a game changer towards the three-cylinder powered motorcycle and to all British motorcycle industries
New offerings
Although the battle between Triumph, BSA and Honda is over, owning a Triumph Trident or BSA Rocket 3 is really a special feeling
I am aware that the three-cylinder machine sports more overall parts and a complicated engine design to what is seen as "normal"
Those that are courageous enough and mechanically inclined will be able to reap the benefits and enjoyment of a three-cylinder machine that a twin-cylinder simply can't produce
Owners and riders alike of a three-cylinder machine will understand that parts will wear and will eventually need to be replaced
Here at Classic British Spares we understand that there are not many parts options or availability for three-cylinder machines and today we wanted to share with you news that could you benefit from

The R3/T160s can be converted to electric start but there is not a simple “universal” kit that can be put together due to wiring and battery location differences (unless you do not mind throwing away unneeded duplicate parts). Pre -’71 bikes need an additional start button. Vertical split Lucas switches have a spare button on the right cluster (W/R wire) that was later used on the T160 for starting but the wire connector and harness does not have the terminal included.
The R3/T150 clutch basket does not have a mount for the ring gear so either an abutment ring has to be brazed on, a T160 basket used or an aftermarket clutch with ring gear.
Using a T160 clutch housing the T150 gearbox flange has to be trimmed for clearance (not a problem with the R3). Also the carb float bowls will sit on the starter motor unless drainless bowls or angled inlet stubs are used to lift the carbs.
The breather port on the T160 clutch housing is in the wrong location for the early breather pipe and interferes with the T150 fuel line.
A larger battery of at least 10 AHr, 12 AHr preferred, is needed. Ground wires from the harness have to be rerouted directly to the battery. If the starter ground wire becomes loose the starter will burn up the harness in short order.
A starter cover is needed for safety. Dripping fuel in the motor then starting is likely to cause a fire.
Finally, T160 clutch housings are near extinct because of the available aftermarket starter. A new clutch housing without the problems is in the works.

I will look into a conversion for the pre-T160 models. I will keep you all up to date on this.
Thanks for the feedback!
