In aluminum and delivered with a 2-part high compression cylinder head with hemispherical chamber, this TNT is directly classified in the RACING range.
The finish is really perfect and despite the reputation that we sometimes hear on TNT, we as connoisseurs and preparers simply find this sublime cylinder for such a small price!
The cylinder head is very well worked with this hemispherical chamber, with stud and high compression, no concern for an increase in performance while preserving good cooling.
The piston is equipped with 2 thin segments so as not to brake at high speeds but to preserve torque, this piston also has side grease nipples to maintain the oil and help the engine greasing.
The cylinder is really good, the finish is impeccable, it has a boosters exhaust and slightly increased diagrams for a little more performance. It is obviously delivered with its gaskets, its cylinder head cover, its clips, its piston pin ...
Mounts on DERBI and APRILIA 50cc motorcycles after 2006 with euro 3 and 4 engine!
As an option we offer a stage 1 preparation, this preparation is a modification of the channels and the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement to the piston and the bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
