Ultima Black Gem Engine

Just after the frame, the choice of an engine is the most important decision to make when building a bike from the ground up. Power, reliability, warranty…and looks. Regarding this last aspect, most of the engines I use on my customs go through the beauty look process. Polishing, powder coating in part or in full, even applying 1-stage heat resistant paint work. In any case it will require a fully disassembled engine, application of the treatment of your choice, then a meticulous reassembly. Always aesthetically worth it, but with a lot of time & money involved. But if you are looking for a complete blacked out engine ready to be dropped in your frame, Ultima Products now offers a “Black Gem Motor” available in the most popular El Bruto 113 ci & 127 ci displacements. The treatment applied is black nickel plating and the warranty is the same as the other Ultima engines. Contact your local Midwest dealer for pricing & more information.

    Who is Ultima ? Can you call them and talk to a technican ? Is Ultima American engineered and American made ? Are the engines any good ?

    Well, BigHand to my knowledge they are made in the state of Missouri, in the USA, and I know quite a few builders that use there “El Bruto” motors, I like them, just my two cents.

    I have a 127 c.i. El Bruto in my personal bike and it has much horsepower and torque, A much stronger engine than the S&S 124. They need a really good induction and short , step-tuned pipes to get maximum flow through the heads , but they do flow! Mine has been to 106 M.P.H. in 6th gear at 3000 R.P.M. : redline is about 5500 R.P.M. My only problem has been the check ball staying open on the oil pump and allowing it to wet sump and not getting to ride enough. The cases are on the S&S design but are beefed up in the right places and more fin area. Not as cosmetically pleasing as an S&S engine but stout. They claim to be made in the U.S.A. and you don’t have to sign up with a bunch of other vendors to get one. They have excellent rod to stroke ratios. I know it sounds like I work for them but I just love horsepower and these El Bruto engines have that.

    So does anyone really know where they are manufactured? I’ve heard Mexico and China mentioned.

  5. 5 Jeff Nicklus Dec 23rd, 2008 at 5:59 pm

    The engines are in fact built in Missouri, not Mexico or China …… as far as I am aware the engine is 100% American Made. I have used several without complaint.

    Over & Out,

    I am a Canadian distributor for Midwest Motorcycle Supplies,they produce and sell the Ultima Products,I have used many Ultima engines in customer builds as well as my own rides using 96,100,113,127 engines. The 127 is not for the feint of heart,I use the 113 in all my Rockstars I sell. Excellent power and torgue with very good fuel milage to go with it. You must use better pipes I recomend 2into 1 Vance and Hines or simalar..If any one needs more advice or a sale ,I can drop ship any where in North America. Check out ULTIMA PRODUCTS on the web,yes American Made Rules…

    Can someone help me? I just bought a custom built bike….. ( One off ) it was built in 1995 and I am sure that it has an Ultima Motor…. but not sure what size it is. The serial number stamped on the jug says U 0093.

    I love the bike and it has pleanty of “go”…. but it’s emabarrasing to not know what engine I have.

    Is there any other tips to identify…. short of pulling the engine apart and measuring pistons?

    I too have a custom bike with an ultima motor. It was built in 03. Im not sure which size el- bruto i have. Its supposed to be a 113, but it was also supposed to be an S&S … The ser no is CE03537391. according to their web site, the CE indicates the el bruto family. 100″-121″. 03 is the year of manufacture. The last character is supposed to be a letter that indicates the CI’s. My ser no has one too many characters, and they aren’t letters. Can anyone clear this up for me, or tell me how to get in touch with ULTIMA? I have looked for a phone # on all their sites with no luck.
