RJSPHH Motorcycle Fork Service Tool Kit — 3-piece set with oil-level gauge & spring compressor, M10–M14 adapters

RJSPHH Motorcycle Fork Service Tool Kit is a three-piece workshop set that measures fork oil height, compresses springs and lets you bleed damper rods so you can service most cartridge and inverted motorcycle forks precisely at home or in the shop.

Whether you’re a home mechanic or a professional tech, this kit gives the core tools needed to inspect and adjust fork internals without costly guesswork. The set includes a threaded damper-rod bleed adapter, an adjustable oil-level gauge with metric markings, and a spring compressor that fits common fork sizes. Built to work across five thread pitches and an oil-measure tube marked to 300 mm, it reduces trial-and-error and helps you restore consistent fork travel and damping feel.

How does the oil level tool help me tune fork performance?

The adjustable oil-level gauge lets you set and verify the exact oil height in millimeters, which affects initial travel, damping and front-end feedback. Accurate oil level measurement is especially important after replacing seals, changing oil weight, or rebuilding cartridges. Use the metal tube’s 0.5 cm increment marks to repeat settings from service notes or manufacturer recommendations.

• Measures 0–300 mm with visible metric markings for repeatable setups
• Adjustable ring locks to record exact oil height
• Suits both cartridge and inverted fork designs
• Helps compare before/after settings when changing oil weight

What forks and thread sizes will the kit fit?

The kit covers most regular cartridge and inverted forks by including five common thread sizes in a single tool: M10 x 1.0, M10 x 1.25, M12 x 1.0, M12 x 1.25 and M14 x 1.0. That means fewer adapters to swap and broader compatibility across makes and models. If your fork uses one of those threads, the bleed and compression operations become straightforward without specialized adapters.

• Includes adapters for M10 and M12 in two pitches and M14-1.0
• Works with most modern cartridge and inverted forks
• Reduces need for model-specific specialty tools
• One kit supports different bikes in a multi-bike shop

How do the spring compressor and damper-rod bleed tool speed a rebuild?

The fork spring compressor safely shortens the spring so you can remove the top cap and access internals without straining parts. The damper-rod bleed adapter lets trapped air or old oil exit the cartridge so you can refill and set the measured oil level cleanly. Together they cut the time spent fumbling with springs and achieving correct oil height after service.

• Compressor holds springs compressed for safe disassembly
• Damper-rod bleed tool provides a sealed path to purge air and oil
• Speeds repeatable reassembly with correct preload and travel
• Reduces risk of runoff or spills during refilling and leveling

Who is this for? This RJSPHH kit is ideal for DIY riders, street and track technicians, and small shops that service a variety of motorcycles. If you perform routine fork maintenance, swap oil weights for handling changes, or rebuild forks to restore ride quality, these three tools simplify accurate, repeatable work. The kit ships with one year warranty support for troubleshooting and replacement requests, so you can invest in fork service capability with added confidence.
