bought a new cf moto 450 october 2020 ran it over the winter with my biker thermals on, we now have nice sunny weather so went out on it with my jeans on, and yes the heat is too much for comfort on the leg. i did a quick look at the quads, and the airflow to the manifold is restricted, it could be an easy fix at manufacture but in the meantime i will see if i can install an air flow to the manifold, plus heat wrap the plastic shield
