Kit 90cc high engine Ø50mm PARMAKIT (special racing 46mm) DERBI euro 1 & 2

Attention unapproved part on road, reserved exclusively for tours, runs ...

Here is a rather unique kit of the Italian house PARMAKIT. Indeed, with its diameter of 50mm and 46mm stroke crankshaft, this kit offers no less real 90,32cc torque and power! This model is designed for 90mm rod. It takes an architecture based on the 110cc of the same brand. This 90cc serras obviously based diet higher than 110cc and above all much simpler to use, plus it does not require machining for its passage. The rod 90mm provides better pre compression in Admin / couple. Which is not a bad as well to exploit this type of cylinder, the volume of low engine must be very high in relation to a 50cc for example. This model rod 90mm libéreras slightly high speed (less rod forcing ). The 90mm rod also reduces the piston acceleration speed (engine modification motion). Design unlike 110cc does not require specific machining to pass the cylinder in the housings. However, it will align the housings which is not bad work. With the 46mm race scheduled for this cylinder, it does not stray too engine says square, allowing a couple but also excellent senior diets! The cylinder was very worked, 5 admission transfers are present, one for the back (we all know that the rear transfer has hardly used the activation valves and scanning ...), the side are the number 4 and they are very bulky, plus on the front bottom as most hyper racing big brand cylinder. Level exhaust, PARMAKIT opted to exhaust has booster is most adapted to couple the beast, a large exhaust has booster is very well drawn on the cylinder. The piston is a true vertex in mono end segment (1mm) to fully release the high mode. It is a low domed piston crown. For the cylinder head, it must extract heat from the thermal group (especially for the 46mm race still majorises heating) PARMAKIT therefore opted for a cylinder head stud. The cylinder head stud billet of high-quality aluminum, the room is a very suitable model to the piston / cylinder, hemispherical shape is polished, we regret that the block is not used to maintain aligned Room the cylinder, the pieces fitting is always possible. the cylinder head cover is also very well designed and has an excellent maintains! Anyway ... We could spend hours talking to you this nice monster we pulled out all the PARMAKIT, this kit was really neat to skirt cut point for improving the filling ... The whole thing is really a set quality, well-kept, large study.

We recommend this kit with: PARMAKIT 46mm stroke crankshaft axis 12mm rod 90mm, 28mm minimum carburetion and quality with valves / pipe ... reinforced bearings, cooling good, thorough preparation, efficient lighting, well reinforced clutch, cold candle racing exhaust ...

Optional we offer a preparation course 1, this preparation is a modification of the exhaust port by increasing the charts and improvement of the duct, it increases the cylinder performance. Improved bottom skirt is also included in the amendment. Allow a little extra time for this preparation!
