The FURY S1 is a Handmade exhaust designed for small frame 125cc Vespas. VMC says the design exploits the engine torque from very low revs, and that it works well with long stroke cylinder kits, giving a sound it describes as “gritty” and “rumbly”.
The exhaust manifold has a flange with slotted holes and fits 52, 56 and 62mm stud centre distances to suit a wide range of models. It’s got a 32mm diameter manifold inlet, and it has been tuned to best suit port timings around 120 degree transfer and 180/185 degree exhaust port , but it is adaptable to wider ranges.
It doesn’t fit ET3 and Primavera frames with left side panel toolbox and, on a PK chassis, part of the internal bulkhead supporting the spare wheel must be cut. SRP is £249.99.
