Description
Latest generation Roost BigBore exhaust, designed for 80-90cc competition cylinders and 43-45mm stroke.

As in all Roost exhausts, the finish is impeccable and stands out for details such as the use of O-rings and spring fixing.
The Roost BigBore can be fitted with carburetors up to 32 mm.
