*Notice: This engine is FACTORY ASSEMBLED. Some of our competitors, especially on eBay, offer engines that are self assembled from spare parts at a lower price. Do not take a risk on a non-factory assembled engine!Demon's 114ci 4" bore Engine
Here at Demon's Cycle we saw a lot of potential in Ultima's 113ci engines. However we thought of a few ways to drastically improve the performance of this engine. We went into partnership with Ultima and after reengenering and implementation of our proposals we are happy to introduce all new "Demon's 114ci" motor.
Here are the main differences between Ultima 113ci engine and Demon's 114ci:
The 113 has a 4 1/2 in stroke and a 4" bore. The 113 is an under square motor (more stroke than bore) and has much higher piston speed (linear feet per second) than the Demon's 114" which has a 4" stroke and 4 1/4 bore. We have managed to reduce piston speed in Demon's 114" Motor's.
This reduction in piston speed results in less wear on the cylinder walls and piston skirts. So its the most reliable engine out there on today's market. This is your future engine and we sell it for the same price as a 113" ultima engine with special air cleaner , better rocker boxes and thicker head gasket for more reliability and dependability.
Also, the increase in rod ratio (rod length divided by stroke) lessens the side load on the cylinder walls, reducing friction, heat, and allowing a much more free revving motor.
By utilizing the MWM 248 cam we were able to retain the great torque characteristics down low and with the increased cylinder fill provided by the increased rod ratio, the Demon's 114 will still pull very hard on the top end.
Another advantage of the shorter stroke is that the Demon's 114" is smoother than the 113. Being based on the 4 1/4" bore engine family, the Demon's 114" has the much stronger 3 piece crankshaft used in the 120/127/130/140 series of motors, along with the much stronger rods.
Billet rocker boxes with holes allow for much better cooling and breathing of the engine.
Demon's custom billet air intake system allows for much better air flow and unrestricted performance.
We should mention that the Demon's 114 is .125 shorter than a 120/127 for those early Softail frames that are a bitch to fit a 120/127 in. And, a lot more exhaust systems will fit with less hassle than on a 120/127."Demon's" series engines which are designed to provide our customers with a USA built High Performance engine that was priced to be the best value of any engines now on the market. Ultima's commitment engineering excellence and competitive pricing brought Demon's 114 to life with a completely new design set of castings emphasizing performance, reliability, and value.
All of the castings in these Engines are poured in US foundries and are based on all new CAD designs cast from C355 Aluminum a common US 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.

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. Midwest's commitment to engineering excellence and competitive pricing brought El Bruto to life with a completely new designed set of castings emphasizing performance, reliability, and value.
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.
