Offer 10% more touring
power than .12CV-Rs. [1] |
A real screamer, with very
good low-end pull and an absolutely track-blistering top end. [2] |

This is a high performance
mill, made in Italy from the finest material and with utmost care
and attention to detail. [1] |
The S-25 is available for
installation in any truck or buggy that was built to carry a .21
engine. [2] |
This big bore powerhouse
is designed to push the T-Maxx to the outer limits of monster truck
performance. [3] |
