El Bruto® Series
Ultima 4.00 Bore 107 and 113 CI  Engines & Long Blocks
Ultima® is now offering the new “El Bruto” Series Engines which are designed to provide our customers with a U.S.A. built High Performance engine that is priced to be the best value of any engines now on the market.

All of the castings in these engines are poured in U.S. foundries and are based on all-new CAD designs cast from C355 aluminum, a common U.S. military alloy known for its stability over multiple heat cycles. The engine components are machined on state of the art CNC equipment for guaranteed dimensional accuracy and repeatability. All of our engines are dynamically balanced using proprietary methods to provide the smoothest running engines on the market and now with our new high flow cylinder heads these engines now can boast the most powerful engines on the market as well!! We think that you will agree these engines are the best value anywhere.  12 /12 warranty. d.o.p.

Starting with the proven 120 engine as the basis, the 124 cid was accomplished by
increasing the stroke from 4.25” to 4.375”. This insures the rider of at least 100 ft. lbs. of torque
above 2000 RPM for passing situations. The camshaft was changed to lower the peak torque
RPM and to spread out the torque curve. At the same time the camshaft ramps were designed
to provide quiet, easy on the valve train longevity.

The compression ratio was dropped slightly to allow for the occasional bad tank of fuel without
causing major engine damage. This slight drop in compression also has the effect of smoothing
out the firing impulses for an even smoother ride. Couple these improvements to pistons made
from time proven 2618 alloy and you have a very quiet, powerful, and long lasting engine for
your riding pleasure.

This combination has been proven on the dyno with torque exceeding 135 ft. lbs. and horse-
power exceeding 140. This data was gathered on a Superflow Dyno, which is recognized as 10%
low when compared to Dyna Jet numbers. Add 10% and you get an astounding 148 ft. lbs. and
154 HP! Not bad for a “bagger” engine!
