Triumph - Honda - BSA collaboration

Choppahead Tronsa, Triumph, Honda, BSA in One Bike

Choppahead's Tronsa's name has nothing to do with the movie Tron, if this is the first thing you thought of. Tronsa is a short name Choppahead had to come up with because Triumph-Honda-BSA would not ever do. Believe it or not, but the Tronsa is really what it names says it is, and even more.

A 75 Triumph 'Bonnevilla T140 provided the engine, transmission and the brakes, while the fork and swingarm came courtesy of a Honda motorcycle, while the gas tank and frame have been kindly donated by a '68 BSA.

Now, what's even stranger is the fact that all these parts coming from three different bikes have been matched by Choppahead and are holding together quite well, as the Tronsa is ridden on a daily basis by its actual owner.

The old Bonneville engine was completely rebuilt and Amal carbs have been fitted, together with a Boyer electronic ignition and a custom, hand-made underseat oil tank. The Tronsa contains in fact a lot of other Choppahead custom parts beautifully integrated in this build, but they're just too many to be listed here.

Whereas pretty much every custom bike is “unique”, the Choppahead Tronsa is by far one bike we rarely get to see.
