This is a GENUINELY reluctant sale of my very pretty TRIBSA 750.

Was fully rebuilt back in late 2017 early 2018.

Due to house moves, coronavirus and other projects I have so far only done 200 miles on the bike, so it’s still being run in!

The primary reason for this sale is I am starting on a re-build of a T150 special. As anyone with knowledge of the Triumph Trident would know the engine costs alone are astronomical. So sadly the TRIBSA has to go to make way for, and fund, the new project.

The bike runs very well and sounds great. Most of the initial shakedown has been completed with the head re-torqued several times, carb tweaked and oil & filter changed, but as more miles are put on the bike it may need the head re-torquing again, tappets re-set, carburation checked, fasteners checked for tightness etc.
The belt drive is very smooth, clutch change is light and gear change very smooth too.

The BSA CB32 frame dates from 1959 and the Triumph engine from 1978.

There are dozens of modifications, the significant ones as follows:
Single carb head with 1mm larger inlet valves by The Cylinder Head Shop
Half race exhaust cam and 3 piece timing side main bearing
Balanced crank
New barrels with 8.6:1 pistons
New conrods
New cams
New tappet followers
In fact nearly all internal engine components are new
Breather modification from timing hole
Belt drive running dry
12V electrics
Tri-Spark ignition
Hydraulic clutch
7 plate clutch conversion and SRM light alloy clutch pressure plate
32mm Mikuni round slide carburettor
Spin oil car type oil filter

Shortened plunger B31/B33 petrol tank
Custom made seat
Crossover shaft for to enable right hand operation of rear BSA QD type brake
A65 rear hub with speedo drive
Avon Roadriders
Suzuki GS 550/750 front forks with floating disk and GS1100 caliper
Modified Suzuki GS fork yokes with taper roller bearings
Indicators and modern style switch gear
Brembo clutch and brake levers
2 into 1 exhaust
Hagon shocks

Please note that not all of the pictures show the recent engine breather mod which was added in order to run the belt drive dry.
