I think that Triumph could get serious and explore the power to weight ratios of three brown mountain squirrels running in three wheels. It would kind of be a rotary engine then. Instead of a fuel tank, one could mount a bushel of corn to feed the squirrels.
Then if something happened and one was way in the outback, one could find a replacement power source: lizard, vole, mole, guinea pig, mouse, rat, badger. The snare kit could be kept in the tail.
just a suggestion. Hope you're listening Triumph
Supermoto bikes exist so that 40 year old men who know better can act like total assholes.
