Screw diameter: M8 Screw length: 50mm Screw pitch: P1.25 [Set components] ・Bolt x 2 ・Nut x 2pcs
*There may be changes in product specifications due to manufacturer's reasons.
By replacing the bolts with titanium bolts, the unsprung weight is reduced, and the strength and visual appearance are improved compared to the stock bolts. The nut is designed to be one size smaller, lighter and more compact. Titanium bolts do not rust semi-permanently because a nonconductive film is formed on the surface. M8 can be installed on off-road and some on-road vehicles (axle block type for bolt-adjustable vehicles) of mainly 4 Japanese manufacturers. M10 is mainly compatible with KTM off-road models and HUSQVARNA.
●Hot forging, machining, and component rolling ZETA titanium products feature a simple design with no unnecessary decorative processing.It focuses on the original purpose of titanium, and there is no unnecessary processing.Not only cutting titanium parts, but also hot forging process is applied to achieve tensile strength that exceeds material strength.The head is precision machined to ensure optimum quality, and because of the high strength of the material, it can be designed one size smaller to further reduce weight.The rolling process is used for the threaded part to prevent seizure and galling.
●64 titanium is used In Japan, it is commonly called "64 titanium", but the correct name is "JIS Type 60" and "TAB6400".The American ASTM standard calls it as "ASTM B348 Gr5" (Grade 5).The notation "Ti-6AL-4V" specifies the chemical composition, which means that 6% aluminum (AL) and 4% vanadium (V) are contained in the mass fraction.It is widely recognized and used as a medical metal for implants, artificial bones, etc.Because of its strength, it is used in aircraft, space industry, nuclear industry, industrial turbines, automobile and motorcycle exhausts, and golf club heads.64 titanium alloy is the most commonly used alloy, accounting for 70% of all titanium alloys.
Lightweight: Specific gravity is about 4.5.Intermediate between iron 7.8 and aluminum 2.8.(55-60% weight of iron) High strength: Tensile strength is more than 900N / mm2, comparable to 930N / mm2 of SCM435 (chromium molybdenum steel). No rusting: The passive film is formed on the surface, so it does not deteriorate semi-permanently. Friendly to people and the environment: Since there is no concern about metal allergy, it is used as an implant and artificial bone.It is also recyclable. Beautiful: It is also used as an ornament because of its excellent corrosion resistance.Various colors can be produced by anodic oxidation. Difficult to process: High technology is required for cutting, press forming and welding. High price: In addition to being a rare metal, it takes time to refine and is difficult to process. Seizure and galling: Weak against friction and prone to seizure and galling.
●Comparison in Strength between types of titanium and other Metals
Pure titanium: It is less expensive than other titanium alloys.Excellent in corrosion resistance but low in strength. α alloy: Excellent in creep resistance (deformation rate against stress for a long time).Excellent in welding work, but poor in workability. β alloy: It has the highest strength among the titanium alloys.It has excellent processability, but the production cost is very high. α-β alloy: It has high strength, ductility and toughness, and excellent workability.ZETA titanium products are made of Ti- AI-4V with alpha-beta alloy.
Points of Attention

Zeta makes some of the best quality parts I have used in my 20+ years of riding motorcycles. These Titanium Axle Bolts fit perfectly and are more easy to install than the stockers. I did use some assembly lube on the threads that go into the swingarm just to help with any future adjustments and to dissipate any moisture that may get in there.These Zeta Perfect fit, i feel much more comfortable with these compared to worrying about the cheap factory bolts. I accidentally rounded off the factory nuts and these are a very solid replacement! Super light weight and strong. Even the price is low for such nice bolts.View Detail
Titaniumium Chain Adjustable Bolt/Nut set Item number:ZT38-5501
Installed on a GSX-R1000R 2019
On Webike's product page, only the Off-road model is listed as a compatible model, but the ZETABrand website clearly shows the On road model as well. HP→https://www.dirtfreak.co.jp/moto/products/zeta/merchandise.php?mode=10&id=bolt/titanium/chainadjusterbolt
It's a chain adjuster bolt. It goes without saying that the Titanium is lighter, but that doesn't mean that its driving performance is any different.
However, if you want to use titanium for the chain adjuster bolt, you have to choose this one because the shape of the universal titanium bolt is not replaceable. I'm rather grateful to ZETA for commercializing such a niche part of the market.
R1000 (L7) When installed on the OEMBolt, it will be about 5mm shorter than the OEMBolt, but there will still be plenty of clearance. In fact, it works fine.
The bolts on the undercarriage inevitably rust and become unsightly, so I feel a certain amount of gratitude for the titanium conversion. However, it is indeed a bit expensive; I wish it was at least another 1000 yen cheaper;View Detail
When I let the shop touch the chain around the wr250x, R and Large body chain, it seems that they do not understand how to tighten the chain adjuster except for Yamaha's official shops, and the adjuster nut is loose after 100 miles. Well, I don't care about it too much because I'm going to re-tighten the Rear Axle Nut and do some other things by myself anyway, but I was worried about the deterioration of the adjuster bolt when I checked it every 500 miles the other day. The difference from the OEM bolt is probably the effect of the bushings, but I feel that the chain is not loose and the axis gap is gone. The appearance is also tightened by Titanium, so it is one of the most popular parts and I feel very satisfied with it.View Detail
Perfect fit, I feel much more comfortable with these compared to worrying about cheap factory bolts. Factory bolts can break. I accidentally rolled the factory nuts and these are a very solid replacement! These Zeta titanium adjustment bolts are deceiving. Super light and strong. Even the price is low for such beautiful bolts. We use it for KTM. I recommend this.View Detail
