TOP PERFORMANCES TPR aluminum engine pack.
This pack comes with a normal stroke crankshaft, which means that it does not offer more than 77cc of displacement.
This allows you to rest any kit on the crankshaft in case of tightening and avoid complications.
The TPR 2 delivered is a model with high diagrams (193 ° / 130 °), a 2-part stud cylinder head for better cooling, the crankshaft is an ultra reinforced model with super balancing, the whole is delivered with bearings and spy seals for a relatively low price!
To be accompanied by a racing variator, a carburation of at least 23mm, a variable advance ignition, a TPR racing exhaust (between special axis of 51mm increased because the cylinder duct is increased for more performance ).
As an option we offer a stage 1 preparation, this preparation is a modification of the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement to the bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
