MZS 8mm Swingarm Spools M8 Pair — 304 Stainless Steel Black Finish, Corrosion-Resistant with Mounting Hardware

MZS 8mm swingarm spools are corrosion-resistant 304 stainless steel bobbins that let you lift and secure your motorcycle on a paddock stand while protecting the rear swingarm from scratches and tip-overs.

These M8-sized spools are engineered for riders who want a robust, long-lasting mounting point for rear paddock stands. Machined from 304 stainless steel and finished in black, the pair of spools includes mounting hardware so you can fit them quickly on compatible motorcycles. They serve as a load-bearing interface between your swingarm and a stand, reducing wear to the swingarm and making maintenance or storage simpler.

Will these spools fit my bike?

These spools are designed for motorcycles that accept M8 sized swingarm bolts. They suit many modern street, sport and adventure bikes, but not every model; some bikes use M10 bolts and require a different kit. Check your bike's factory bolt size or consult the vehicle fitment list before purchase.

• Standard thread size: M8 spools and screws included
• Common compatible models: many CBR, GSX-R, GSXS, SV650, V-Strom, Z and ZX series
• Not compatible with specific M10-equipped bikes (see fitment exclusions)
• Reference the store fitment list for exact year/model compatibility

How durable and weather-resistant are these stainless steel bobbins?

The spools are manufactured from premium 304 stainless steel, which offers excellent corrosion resistance and long-term aesthetic stability. The material resists rust and fading under normal road and garage conditions, and the design tolerates heavy loads without fracturing.

• Material: 304 stainless steel for corrosion and wear resistance
• Load performance: engineered to resist bending and survive impacts
• Finish: black-treated surface that maintains appearance over time
• Included hardware matches the spool material for a secure fit

How easy is installation and what hardware comes in the box?

Installation is straightforward and usually requires no drilling or modification—bolt the spools into your swingarm using the supplied screws and washers. The kit includes additional sleeves and washers to help achieve a flush fit against different swingarm designs.

• Contents: 2 spools, 2 M8 screws, 4 washers, 2 sleeves
• Tools needed: basic sockets or hex keys—no special tools
• Adjustment: use included washers/sleeves if the spool does not sit flush
• Support: technical help available from MZS if parts are missing or damaged

Can these spools protect my bike during parking and maintenance?

Yes—when used with a compatible paddock stand, the spools create a stable lift point that reduces the chance of swingarm contact or bodywork scratches during storage and servicing. They act as sacrificial contact points that take the brunt of drops or knocks, helping preserve expensive swingarm finishes.

• Primary use: lift and stabilize bike on a rear paddock stand
• Secondary benefit: lowers risk of scratches and tip-over damage
• Design focus: distributes load to prevent concentrated swingarm stress
• Practical: ideal for cleaning, chain maintenance, or garage storage

Who is this for? The MZS 8mm swingarm spools are aimed at riders who own motorcycles that accept M8 swingarm bolts and want a strong, long-lasting solution for paddock-stand use and rear-end protection. They’re a practical choice for home mechanics, track-day enthusiasts, and anyone wanting a tidy, damage-reducing way to store or service their bike. If your motorcycle uses M10 bolts, look for the corresponding MZS M10 kit available separately.
