Not homologated on public roads, only reserved for competition, does not respect the highway code in any way!
A very good kit whose reputation is second to none, this beautiful kit is the well-known and renowned TOP ROSE with stud, it is certainly in cast iron but treated with MINACROM and in a domed hard chrome mono segment to allow the highest speeds, diameter 49.5 millimeters, reinforced piston in thin single segment, very advanced diagrams based on mid-torque/mid high-rev, it has as usual on new motor parts grease nipples under the sides, the kit is very clean and finished . It is the evolution of the normal pink Top performances thanks to its stud bolt (bolt in 2 parts) and its reinforced needle cage included in the kit. This cylinder head has a polished tapered high compression chamber and therefore allows relatively good performance.
We recommend it to those who want something between big power and solidity, after its color depends on everyone's taste, some will like it, others not but it is the most powerful 80cc cast iron kit in normal race with the POLINI d.50mm melting. We will be able to make it reach even more power thanks to a preparation because the piston is really not worked enough on this type of kit.
As an option, we offer you a STAGE 1 preparation, this preparation includes a selection of the best part from our stock, a marked improvement in the shape and the exhaust diagram as well as a special retouching of the cylinder skirt and the piston. for better sweeping/filling according to our best tests. An improvement in lubrication is made on passage in view of the speeds obtained after preparation. This preparation requires an additional period of 2 to 15 days depending on our availability! It requires tools and around 4 to 5 hours of work on this cylinder. The price is therefore accordingly.
