One of my friends studied at McGill University and he was part of the team that built the real MRT5. The MRT5 was intented to compete in the Formula SAE, in auto-X layouts and karting circuits. ( Although, they practised on Gilles-Villeneuve circuit or the Monteal Casino's parking lot
)
So, to sum up, yes the MRT5 can be used as a kart.
I went to the McGill openhouse last weekend, they were buiding the new MRT7. Kawasaki engine ( unknown specs) and a supercharger... Only if I brought the camera...
did I mention CF rims?
