TL;DR: The AM6 clutch cover guard by STR8 is a CNC anodised aluminium piece that fits over the stock clutch cover of any 50cc bike running a Minarelli AM6 engine in minutes. It protects, looks great, and costs far less than a full cover replacement.
🏍️ Why protect your AM6 clutch cover?
The AM6 clutch cover is one of the most exposed parts on a 50cc geared motorcycle. Kick-starter strikes, mud, stones, and minor spills all leave their mark on the stock cover over time. Once scratched or cracked, it becomes an eyesore that’s hard to ignore.
Rather than spending on a full CNC-machined AM6 clutch cover replacement — which can be expensive — or riding around with a battered case, STR8 offers a smart middle-ground solution: a guard that slips straight over the stock cover without replacing it. The result is effective AM6 engine protection, a proper racing look, and a budget kept firmly in check.
🔩 Design and materials: CNC aluminium for a racing look
The STR8 AM6 clutch cover guard is machined from a solid block of CNC aluminium and then anodised, delivering a dual quality:
- ➜ Mechanical strength: aluminium absorbs impacts and effectively shields the stock plastic or aluminium cover.
- ➜ Premium finish: the grooved-effect machining (parallel channels) gives it a look straight out of motocross and enduro.
- ➜ Durable anodising: the colour is locked into the material and resists wear, UV and mud splashes.
This manufacturing philosophy, typical of all STR8 parts, places the AM6 engine guard squarely between a cosmetic accessory and a serious protection part.

⚙️ Installation: quick and easy, no specialist skills needed
Fitting the STR8 AM6 clutch cover guard does not require removing the stock cover. The guard bolts directly over it using the 3 bolts and 3 spacers supplied in the kit.
Recommended fitting steps
- ➜ Take advantage of a gearbox oil change to fit the guard (the bolts pass close to the drain/filler plugs).
- ➜ Clean the surface of the stock cover before fitting to avoid trapping grit underneath.
- ➜ Align the guard so it sits flush against the AM6 cover contour.
- ➜ Tighten the 3 bolts in a cross pattern for even pressure — no excessive torque needed on aluminium.
Matching accessories for a cohesive look
For a truly unified finish, STR8 recommends pairing this guard with:
- ➜ The STR8 oil pump blanking plug from the same series
- ➜ The matching STR8 gearbox oil filler cap
These three pieces work together as a visual set and show real attention to detail on your 50cc build.
