DescriptionThe whole story▼
Getting your Kawasaki ZX-4 RR up on a rear paddock stand should be effortless, and with these purpose-made 8mm bobbins from Hesterberg-Cad/Cam it genuinely is. Machined from aerospace-grade 7075-T6 aluminium and finished in a clean factory style, they give you defined, secure lift points on the swingarm every single time — whether you are chasing a lap-time setup in the paddock or running a quick chain service in the garage.
Key Features
- Precision-fit 8mm spool design engineered specifically for the Kawasaki ZX-4 RR swingarm, model years 2023 to 2026
- Machined from 7075-T6 aluminium — one of the strongest alloys used in motorsport applications — keeping weight to approximately 0.060 kg per pair
- Defined lift points protect the swingarm from direct contact with stand hooks, reducing wear and cosmetic damage
- Equally at home during tyre warmer sessions, chain maintenance, wheel or brake work, and full trackday preparation
- Factory-style finish sits cleanly on the ZX-4 RR's aggressive supersport bodywork without looking like an afterthought
- Supplied complete with M8x30mm mounting bolts — no additional hardware needed for a straightforward installation
Built for Riders Who Take Maintenance Seriously
The ZX-4 RR is a compact, high-revving supersport machine that rewards precise preparation. Every component on it — from the four-cylinder engine to the chassis geometry — is tuned for performance, and the ancillary parts that support it should match that standard. Hesterberg-Cad/Cam designs these bobbins with exactly that philosophy in mind: functional accessories that perform without fuss and look the part on a serious bike.
Using a rear paddock stand without dedicated spool points is a compromise that shows under pressure. These bobbins eliminate that compromise entirely, giving the stand a consistent, repeatable grip point that keeps the bike stable while you work. Chain lubrication, sprocket inspection, tyre swaps between road and track rubber, rear brake bleed — all of these tasks become noticeably smoother with the bike sitting securely on proper stand spools rather than balanced on improvised contact points.
From the Workshop to the Paddock
Whether you maintain your ZX-4 RR at home, have it serviced at a dealer, or prepare it yourself at a circuit, a rear paddock stand is close to essential kit. These bobbins complete that setup by giving the stand a proper interface with the swingarm. The low mass means there is no meaningful addition to unsprung weight, and the anodised aluminium finish resists workshop chemicals and everyday abrasion without demanding special care.
For trackday regulars, the efficiency gain is immediate: the bike goes up cleanly, tyre warmers slide on without wrestling with the chassis, and the bike comes down again just as smoothly. That predictability matters when time in the paddock is limited and your focus needs to be on riding.
