The famous AIRSAL ROUGE X-TREM special for 45mm stroke, power and a lot of torque for a reduced price on your DERBI euro 3 and 4 motor bikes.
Here is the last born of the house AIRSAL for DERBI euro 3 and 4! The Spanish brand has embarked on a superb challenge: to release a high performance ultra racing engine at an unbeatable price.
Successful bet as proof with this high red 88cc Ø50mm AIRSAL Xtrem engine. This model is really beautiful, powerful and ingenious, all for a price that could not be more reasonable.
The cylinder is therefore a Ø50mm, it is intended for a 45mm stroke crankshaft with a 90mm original size connecting rod like the special 88cc AIRSAL or BARIKIT 45mm stroke crankshafts. This Ø50mm and 45mm stroke ratio offers no less than 88, 35cc.
This cylinder is not only painted in red, it is an entire architecture that has been created! The rear admission receives 3 transfers in order to improve the sweeping, the lateral ones are 2X2 and they are well worked on the whole.
The exhaust is a very large bar model with boosters on each side. Nykasil is an ordinary scanimet (we would still prefer a high-end coating like hard nykasil but it is already of good quality).
The diagrams are high in order to offer maximum performance at high speed, the torque will still be very present thanks to the 45mm stroke. The cylinder head is an ordinary one-piece, we would still have preferred a stud bolt to improve cooling and changes in volumes, shapes ...
But this monobloc cylinder head will already amply satisfy 99% of users! The chamber is a high compression hemispherical model with a polished finish, the assembly offers a compression ratio of 13: 4 (squish recommended 0.70mm).
The piston is an ordinary VERTEX model that is often found on AIRSALs, it is of very good quality and it is specific thanks to its anti-detonation treatment on the shell.
This piston is equipped with a Ø50X1mm chrome domed nodular segment to allow the highest speeds. The piston is equipped with side grease nipples which is also very appreciable for longevity.
The attached pack is complete but you will still lack base gaskets to make the squish as it should be, which is unfortunate!
In conclusion, this set is truly superb value for money!
The performance will be there for sure with such a high engine.
It is clear that users who want very polished hardware will regret the lack of solid studs with nuts, a hard nykasil, a stud bolt, gaskets to make the squish properly ...
But for such a price we couldn't expect anything better than what AIRSAL did! The finish will certainly amaze you!
It is worthy of the greatest BIDALOT, MHR ... See even better!
