OnZa Bar Ends


Onza had made for them in Taiwan and imports to the United States, several models of handle bar extensions, the OZ-120 is one such set. The cinch assembly is made from cold forged and machined aluminum. Cold forging is the process of squeezing, in this case aluminum, repeatedly using different shaped dies until it assumes the shape you finally desire. This makes a denser and more sturdy piece. The hole is drilled up from the bottom of the cinch assembly for the cinch bolt. The bolt hole recesses the bolt head, and makes the pilot hole for the threads which are then tapped. The cinch piece is sawn through, from the front into the handlebar hole to make the clamping mechanism. The clamp is a low profile design leaving more hand room on the handlebar. The cinch bolt with washer are made of Nickel plated steel having an 8mm x 1.25mm pitch thread pattern that is 18mm long. At this writing there is no known Titanium replacement bolt available to replace this 7 gram steel bolt with. The grip tubing section is made of aluminum and is 4 5/8 inches long. It is press fit and epoxy bonded to the cinch assembly, giving it a 12 degree from handlebar perpendicular inward angle toward the front tire. As a ski-bend type bar end, there is a bend toward the end of the grip tube. It bends further inward at 60 degrees and upward 40 degrees. OZ-120 bar ends come with Black plastic press-in grip tube end plugs installed. There is also a pair of Black plastic press-in handlebar ends plugs. The clamp is Silver, the grip tube is Black or Silver, and the pair of OZ-120 bar ends with all plugs weighs 162.5 grams. We sold these for $24.99 a pair


The Onza OZ-170 bar ends use the same bolts and end plugs, and a very similar cinch assembly to those that are used in the OZ-120 set. The low profile clamp leaves more hand room on the bar. Please read above for the description. The cinch assembly on the OZ-170 extends the grip tubing forward by 1/8 inch, though it holds the grip tube at the same angle. On the OZ-170, the grip tubing section is in the form of an L-bend using a 6 3/4 inch piece of aluminum tubing. The grip section starts with the 12 degree angle generated by the cinch assembly, then extends for 2 inches where a bend occurs. The bend turns the grip tube inward to the front tire by an added 60 degrees and upward by 14 degrees The clamp is Silver, the grip tube is Black or Silver, and the pair of OZ-170 bar ends with all plugs weighs 191 grams. We sold these for $24.99 a pair.


The RCR bar ends are ski bend, cinch type, made of Co-Moly steel tubing. They appear to be made in a factory other than the RAW series, and the work resembles the Dewey and Dewey 2 bar ends. The cinch tubing is a 1.2mm wall thickness Cro-moly steel. The RCR cinch tube has diagonally cut sides flaring away from the rider. The rider's side is 17mm wide, while the grip tubing side is 23mm wide. The cinch fitting is machined from Cro-moly steel rod, cut to length, drilled to recess the cinch bolt head and create the pilot hole for the tapped threads. The fitting rod is tapped for the bolt threads, then welded in place. The grip tubing section, made of Cro-moly steel, is approximately 6 inches long, and has a .7mm wall thickness. The 21.7mm diameter grip tube is crimped to become just 18.5mm wide at the clamp, making this a "low profile" styled bar end. The grip tub is miter cut to contour the clamp tube then TIG welded to it. The grip tube is welded to produce a 14 degree inward angle. The ski bend occurs at the 3 3/4 inches from the cinch assembly with the tip rising at about 60 degrees. The clamp is cut through to make the cinch mechanism and the entire bar end is plated with a nickel finish if Silver or painted if Black. The cinch bolt has 6mm by 1mm pitched threads, is 15mm long, has a 6mm hex fitting, and weighs 5 grams. The RCR 160 bar ends come with Black plastic press-in plug installed in the grip tubes. There are no plugs included to cover the open handlebar end. These are the same plugs used on the Onza RAW series, yet these have no Onza logo. Available in either Black or Silver, a pair of RCR 160 bar ends weighs 172.5 grams. We sold these for $16.99 a pair.



The Onza MT-74T bar ends are made of that mystical metal that hard core riders have shown such a monstrous desire for. These are an "L bend" style, but rather than being bent, the grip section is made of two 3 1/2" tubes as a primary and secondary grip section. The cinch assembly is made of 1.4mm wall thickness 3Al- 2.5V Titanium tubing cut to a 1 3/16 inch length, which will become "width" on the handlebar. The cinch fitting is machined from Titanium rod that's cut to length then drilled through. The drilling leaves a larger bore at the front to recess the cinch bolt head, and finishes with a narrower pilot hole for the bolt threads to be tapped from. The grip tubing sections are made from 1.2mm wall thickness Titanium tubing. Both pieces are 3 1/2 inches with the joining ends being miter cut to contour its adjoining piece for full contact when they are TIG welded together. The primary grip section is TIG welded to the cinch assembly at a 15 degree angle, from perpendicular to the handlebar, inwardly toward the front tire. The secondary grip tubing section is welded at an additional 57 degrees inwardly from the primary grip tubing section. The secondary piece also adds a 10 upward angle to the secondary grip tube. The cinch fitting is the last piece welded to the bar end, then the bottom of the cinch assembly is cut through in the handlebar direction to make the clamping mechanism. A nickel plated steel bolt and washer are used for the cinch bolt. The bolt has a 6mm allen head fitting with 6mm x 1mm thread pitch, 20mm long weighing 6 grams. Onza includes 2 Rodon Black plastic press-in end plugs for the open grip section tubes, and 2 molded Black rubber boots that enclose the handlebar end and cinch assembly. The pair of rubber boots weigh 33 1/2 grams, with the press-in end plugs weighing 5 grams. With the Black boots, end plugs, and steel bolts, a set of MT-74T bar extensions weighs 188.5 grams. These were made in Washington, USA, but no longer. We sold them for $139.99 a pair.
