AGRAS' KATANA

1126_KATANA_01.jpg

AGRAS has been developing high-quality machined aluminum parts for many different models using their in-house NC machining center for many years. With a strong focus on Suzuki bikes, the company has released parts for the modern KATANA since its release in 2019. The most noteworthy of these are the handlebar kit, which was the first to be commercialized by any aftermarket company, and the various engine sliders, which are the brand's specialty.

"For the handlebars, even before the release of the KATANA, we were thinking that many people would want to change the position, so we started planning, and once we had the actual bike in hand, we tried various ways to make it work. The tank cover is high, and there were many places where changing the position would cause unexpected interference, so it was difficult to find space. At one point, we thought about reducing the handlebar steering angle to prevent interference, and to that end, we thought about including a handlebar stopper and a special handlebar lock, but doing so would increase the price, and more importantly, the larger the steering angle, the easier the bike is to maneuver, so we tried our best to leave that at the stock angle. We also made a jig and modified and attached junk parts from previous products to create the production data, which we used to create the top bridge and clip-on handlebar kit," says Mr. Kuboyama of AGRAS.

If you look closely at the photos of this kit installed on the bike, you will notice that while ensuring strength and texture, it is also designed to avoid interference. The position of the handlebars is a little bit forward and lower than the stock position, and the drop angle is 10 degrees. The look of the machined parts, which are AGRAS' specialty, matches well with the cyber-esque design of the KATANA, and the position of this kit makes you want to try it out.

Engine sliders, which are available for a wide range of models, are also a standard item from AGRAS. The engine sliders for the KATANA, which are designed to match the different appearances of the left and right sides, have a base made of machined A2017 aluminum which is buffed and anodized. The polyacetal resin slider is then mounted on top of that base, consistent with past designs, for an improved look. “For the KATANA, we also added a newly designed slider that connects the front and upper engine mounts and also serves as a frame reinforcement,” says Kuboyama. Other exclusive items include an external helmet holder, and for the steps and non-engine sliders, parts previously released for the GSX-S1000 can be used. AGRAS' high quality, practical parts are a good match for the KATANA, and something to check out even if you're not a KATANA owner.

Handle

Machined top bridge (upper right) and other parts. The handlebar is in the foreground. The top bridge is wing-shaped, and the back side has cutouts for weight reduction. The top bridge kit does not change the height of the handlebar, but the position can be set to 10mm forward, 0mm, or 10mm back, and there are two types; one for the stock tapered bar and the other for a standard φ22.2mm bar.

Photo of the Clip-on Handlebar Kit installed. The bar clamp is placed on top of the mounting parts which extrude from under the machined aluminum bridge. The bar goes a little further forward than stock but the stock cables can be used. The look of the handlebar area and the overall impression of the KATANA itself can be changed.

Seen from another angle. The top bridge is replaced, mounts attached to the left and right sides, and the bars placed on them. Clearance for each part is also considered. Note that this photo shows the top bridge included in the Clip-on Handlebar Kit, which is a different product from the top bridge for standard pipe handlebars.

Engine

The racing slider that protects the crankcase is a standard AGRAS product. A polyacetal slider is stylishly combined with a machined aluminum A2017 base. The front side of the engine showcases a uniquely shaped part that connects the engine mounts (in this photo, a paper pattern used to confirm the size is attached; the product itself is visible in the full photo of the bike at the top of this article).

There are three types of racing sliders that attach to the generator cover on the left side of the engine. The photo shows the “Generator C” type, which has an aluminum base that attaches using the generator cover bolts, with a slider made of Duracon mounted to it. There is also a “Generator A” type with a V-shaped aluminum base and a “Generator B” type with just the Duracon slider. The slider that attaches to the front side of the frame is also available in three types.
