A very large, solid and very efficient kit to be placed next to the aluminum TPR, in aluminum and high-end treatment, revised and corrected admission, diameter 47.6mm, finish worthy of the largest kits, cylinder head with high compression tapered polished chamber, in short , a concentrate of performances made in Italy. Having tried it a lot and sold it a lot, it is a really powerful kit, very torquey, also a lot of high speed, with good settings, a good squish (several base gaskets are also delivered), you will be able to reach really big performances.
The pack also includes a set of competition carbon valve slats to adjust the intake with the high engine. It is in piston pin of 10mm or 12mm to choose from, its piston is in hard chrome domed mono segment and adapted to the cylinder, we will be able to see the small preparation on the rear skirt and the maximum opening on the sides just below the rods of reinforcement. This kit will prefer the torque at high speed by its diagrams and its normal exhaust. If you want a very high speed and even more advanced kit, see the ATHENA 47.6mm aluminum racing version, there are also the special long stroke versions ... ATHENA takes up a huge place with products that are always less expensive, more efficient, clean, and a huge catalog. The RRD team has chosen this kit to cut the first step of the low-cost aluminum kits in part thanks to its quality and performance.
