TM Manufacturer Engine

TM Manufacturer Engine

The philosophy that has always distinguished TM is without doubt the choice of materials, which must always be of the highest quality, and the workmanship, even defined by some as “obsessive”, not to mention the high performance of the engines used on the standard bikes, in many cases far superior to those of the most prestigious competitors. This justifies the prices of these jewels of engineering that appeal to a niche market made up of very demanding customers. They can in fact purchase a standard product with which to race in high level competition.

All the rest is recent history.
