Not homologated on the road! Reserved for competition.
This kit is excellent and certainly the strongest with the BLACK TOP, we recommend it in several cases, to replace the original with power and torque gain, especially for those who want a very good kit at a low price, for the price it's very surprising, the quality is here, grease nipples under the sides, bore really very clean!
Cylinder head level, the tapered and polished high compression combustion chamber, Ø49 millimeter piston (73.54cc real) reinforced, high quality cast iron, high-performance diagrams with a great torque / power ratio, large exhaust and so on, really very beautiful material which in terms of performance is really amazing, it is identical to the black performance top, it is really an excellent compromise between low price, solidity and performance. Also in MINACROM cast iron (patent filed by MOTORPARTS which is none other than MINARELLI MOTORI ITALY) and two segments (curved chrome steel segment) therefore very solid and very discreet in color. Some do up to 25,000 km without worry by changing the piston at 10,000 km. In case of tightening or for more power you can rebore it at a lower cost in d.49.5 mm and easily find piston / cylinder head / rings... You can also adapt the piston of the pink top performance by reboring in d.49, 5mm. Made at motorpart ( TOP PERFORMANCES / DR / MINARELLI group...)

We advise to mount at least to accompany this kit:
17.5mm carburetor/reinforced bearings/cold competition spark plug/tuning/racing exhaust
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.
