Demon's Cycle Inc. and Ultima Motorcycle Products have teamed up to produce and make available to the Performance oriented motorcycle public a motor that has never before been available and which will become the new standard by which all V-twins are compared. As a competitor, it by far exceeds the capabilities of engine offered by Harley-Davidson. The new design configuration is built upon tried and proven engine configuration but is clearly superior in all respects and vastly outperforms the competition in many ways.

Not just another quality engine. The designers of this high performance model built in too many features to list but the most distinguishable are noted below. Demon's Cycle and Ultima are foremost in cutting edge performance related style and quality mechanical innovation. The new engine offered here clearly demonstrates that they have found the secret which others had previously sought after but have come up short until this time. Here are some of the differences and advantages of the new Demon's 114 engine in comparison to the Ultima 113 ci engine:

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. They 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 it's the most reliable engine out there on today's market. This is the future engine and they 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 reving 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.

"We have made the first reliable high performance engine ever created. We nailed the task. It will create many very happy customers," says Artem Rodos, Demon's Cycle VP.

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 very difficult to fit a 120/127 in. And, a lot more exhaust systems will fit with less hassle than on a 120/127 engines.'
