Attention, prohibited on the road, only reserved for competition.
Available in 12mm axle only. Here is the BIDALOT racing replica kit for liquid horizontal minarelli, although it bears the name of replica, it is a real competition kit! This cylinder has a real competition architecture very worked, we can notice to start an ultra increased base and well drawn, you will have to align your casings for good performances.
We also notice the rear sides that really pull and the rear transfers, 2 in number. Unlike some cylinders like the MALOSSI MHR TEAM, this cylinder does not require boring the housings at the skirt feet for its passage... stock horizontal minarelli crankcases (mbk nitro, Yamaha aerox, malaguti f12…).
The aluminum is very top of the range, the nicasil is also one of the best on the market. The finish is really excellent, this cylinder has very high diagrams and a large bar exhaust… It will therefore require an exhaust, carburetion and ignition to match! And above all a well-reinforced crankshaft and bearings.
The cylinder head is in 2 parts to offer ease of changing the studs but above all to improve cooling. the pedestal has a tapered chamber with a polished finish. The piston is a top-of-the-range model with a high silicon content, it is equipped with a mono segment end hard chrome domed not to limit the high speeds!
This cylinder is clearly a real monster, it offers a very good torque but above all a very high power... Like what, you should certainly not trust its nice replica name. It is referenced under the number 11000733.
Its differences with the real pro competition reference 11000833 are: The piston which is not forged but a simple casting, the base gasket which here on the replica is alone, the pro competition has several base gaskets to do well the squish and even a racing spark plug or a special 85mm elongated connecting rod wedge delivered with it, the cylinder is obviously less worked on this replica version, even the cylinder head cover and other tricks are also different.
We recommend accompanying this kit with at least : 21mm carburetor, reinforced crankshaft (39.2mm stroke and 80.00 connecting rod of original size but connecting rod small end cage in Ø12mm against 10mm for the origin), reinforced bearings, ignition holding the towers (original minimum improved with box), racing exhaust, cold racing spark plug…

As an option, we offer you 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. Count a little extra time for this preparation!
