Screw Thread Size Guide For 99-07 Hayabusa Models

The Suzuki GSX1300R Hayabusa is a high-performance motorcycle known for its speed and power. While the Hayabusa has undergone several model changes since its introduction in 1999, one constant has been the use of screws and bolts with varying thread sizes. For example, the Titanium Front and Rear Disc (Rotor) Bolt 99-07 Hayabusa has a thread diameter of 8mm and a thread pitch of 1.25mm. Additionally, the side fairing screws on the 99-07 Hayabusa are available in two sizes: M5x16 and M6x20.

M5 screw size

The M5 screw size is a common metric used for a variety of applications, including motorcycles such as the Suzuki Hayabusa. This particular screw size is often used for smaller screws, such as those found on fairings.

The M5 designation refers to the diameter of the screw thread, which is 5 millimetres. This is a standard size for many motorcycle models, including the Hayabusa. The thread size is important as it ensures the correct fit for the screw, preventing stripping or cross-threading.

When working with M5 screws, it is important to use the correct tools and techniques. A tap and die set can be useful for cleaning up threads, especially if they have been cross-threaded or damaged. It is also important to use the correct screwdriver size and type to avoid stripping the screw head.

For the Suzuki Hayabusa, the M5 screw size is used for some of the side fairing screws. Specifically, the smaller screws are M5x16, while the larger ones are M6x20. It is always a good idea to check the specific screw size required for your particular motorcycle model, as there may be variations depending on the year and model of the Hayabusa.

In addition to the M5 screw size, the Hayabusa also uses other metric screw sizes, such as M6. It is always a good practice to have a variety of screw sizes on hand when working on motorcycles, as different models and components may require different sizes.

M6 screw size

The M6 screw size is one of the screw sizes used in the Suzuki Hayabusa 99-07 model. The M6 screw size is specifically mentioned in a forum post about the fairing screw size for this motorcycle model. The user, Kevin-MI, believes that the correct screw size for the two larger side fairing screws is 09139-06087 SCREW M6X20. This information is confirmed by another user, who also recommends using a tap to clean up the threads.

The M6 screw size is also referenced in a product listing for Suzuki Hayabusa 99-07 connecting rods. The listing mentions that the connecting rods include ARP 2000 cap fasteners that are rated at 220,000 psi. The higher the psi rating, the stronger the screw or fastener. The M6 screw size is typically used for larger screws that require more strength and durability.

It's important to note that screw sizes are measured in metric units, with "M" denoting the size in millimetres. So, an M6 screw has a diameter of 6 millimetres. The length of the screw can vary, which is why you see different lengths mentioned, such as M6X20, indicating a length of 20 millimetres.

When working with screws and fasteners, it's crucial to use the correct size and type to ensure proper fitment and avoid damage. In the case of the Hayabusa 99-07, using the correct screw sizes, such as the M6, is essential for maintaining the integrity of the motorcycle's fairing and other components.

Additionally, the M6 screw size is commonly used in various applications beyond the Hayabusa 99-07. It is a standard size that can be found in automotive, industrial, and even consumer electronics industries. The versatility of the M6 screw size makes it a popular choice for manufacturers and repair professionals.

Thread pitch

When it comes to the Suzuki Hayabusa 99-07 motorcycle, thread pitch plays a significant role in maintaining the integrity of the fairing screws. Fairing screws are the fasteners that secure the outer panels or "fairings" of the motorcycle, giving it a sleek and aerodynamic appearance. These screws are subjected to various forces, including vibration and wind resistance, so it is crucial to use the correct screw size and thread pitch to ensure a secure fit.

In the context of the Hayabusa, a user sought advice on the screw size and thread for the side fairing screws. Cross-threading can occur when the threads of a screw and the threaded hole do not align properly, resulting in damage to the threads. To address this issue, the user considered using a tap to clean up the damaged threads.

For the smaller side fairing screws, the recommended screw size is M5, specifically the screw with the part number 09139-05054 (M5X16). This screw size and thread pitch are crucial for ensuring a secure fit and preventing vibration-related issues. The larger side fairing screws, on the other hand, typically require a larger screw size, such as M6, with the part number 09139-06087 (M6X20). By using the correct screw size and thread pitch, you can maintain the structural integrity of the fairings and ensure the optimal performance of your Hayabusa motorcycle.

Thread diameter

The thread diameter of a screw is an important specification to consider when working with screws, as it determines the size and compatibility of the screw with the intended mounting surface. In the context of a 99-07 Hayabusa, a high-performance motorcycle, ensuring the correct thread diameter is critical for both the vehicle's performance and safety.

When referring to the 99-07 Hayabusa, it appears that there are multiple screw sizes and thread diameters to consider, depending on the specific component and application. For example, the side fairing screws, which secure the side panels of the motorcycle, are mentioned to have different sizes. One source suggests that the smaller side fairing screws have a thread diameter of M5, which equates to a nominal diameter of 5 millimetres. Meanwhile, the larger side fairing screws are said to have a thread diameter of M6, indicating a nominal diameter of 6 millimetres.

Additionally, when discussing the front and rear disc rotor bolts of the 99-07 Hayabusa, a specific thread diameter of 8 millimetres is mentioned. This particular bolt is made of titanium and serves the purpose of replacing corroded or rusty original bolts. It is important to note that the colour finish of titanium bolts may differ from aluminium bolts.

It is worth noting that thread diameter is not the only relevant specification when dealing with screws and bolts. Thread pitch, which determines the spacing between adjacent threads, is also crucial. In the case of the aforementioned disc rotor bolts, the thread pitch is specified as 1.25 millimetres.

Given the variety of screw sizes and thread diameters present in a 99-07 Hayabusa, it is always recommended to consult appropriate service manuals or seek advice from experienced mechanics or fellow motorcycle enthusiasts when performing maintenance or modifications.

I accidentally cross-threaded one of the side fairing screws last fall when I put my bike away. I would like to run a tap through it to clean it up. Maybe a M5? Any ideas on the screw size and thread?

I think you are looking at 09139-05054 SCREW M5X16 for the 10 smaller ones and 09139-06087 SCREW M6X20 for the 2 larger ones.

I am doing some rewiring and need the wiring diagram for the Gen 1. I tore it all apart and took the fuse's and relay out but still can't find the wire I need. It's the Red with grey slash marks and orange with grey slash marks for the pass button wiring set up. Any help is appreciated. Thanks!

I have that early manual also, but "flash to pass" was not on early models (99-00). Not sure what year that started.

After countless hours of searching through forums and videos to find info on how to hotwire my bike, I decided to elaborate on how to do it. I bought the bike wrecked; the whole front end was destroyed, and the ignition wires were cut flush with the ignition. The seller told me that the bike ran but had no way of proving it. I know this is not cool, but I was impatient and just had to know if it would start. Please do not steal someone else's bike. Here is a step-by-step guide on how to hotwire a 99-07 Hayabusa.

I am looking to do an HID conversion and need to know what bulb sizes the new 'Busa uses. I don't have the bike near me, so I can't check myself. Can anyone help me out?

Stockers are H-7 Low, and H-9 High.

'99 - '07 = H7-lowbeam, 9005-Highbeam '08 = H7-lowbeam, H9-Highbeam
