Specbolt Fasteners CRF Plastics & Bodywork Fastener Kit — 90‑Piece for CRF150R/250R/450R, 10.9 Heat‑Treated OEM‑Fit

Complete 90-piece Specbolt fastener kit engineered to replace and upgrade all plastics and bodywork bolts on Honda CRF150R, CRF250R and CRF450R dirtbikes.

When you strip body panels for maintenance, crash repair or a fresh graphics job you want a single kit that restores factory fit and finish without hunting down individual fasteners. This Specbolt set bundles 90 high-strength, heat-treated bolts, modern-style fork guard and side panel fasteners, the three common Honda seat bolts, and the two square nuts found on recent CRF fenders — everything sized to match OEM locations and withstand off-road use.

What exactly is included and how does it match my CRF model?

The kit contains a comprehensive selection of bolts, nuts and shouldered seat fasteners intended to replace the plastic-attachment hardware on 4-stroke Honda CRF models. Specbolt used 10.9 grade heat-treated steel so the parts have comparable strength to OEM units.

• 90 pieces total: bolts, square nuts, shouldered seat bolts and spares.
• Full M6 sets for modern fork guards and side panels.
• Includes two square nuts for contemporary front/rear fender mounting.
• Three seat-bolt styles to fit different CRF variants (150R/250R/450R).

How will this kit simplify repairs after a crash or during routine maintenance?

Instead of sourcing individual fasteners, the kit gives you all common replacement hardware in one box so you can reinstall plastics immediately. Having spares on hand eliminates delays and ensures you can reuse original panels without improvising with mismatched bolts.

• Replaces front and rear fender, shroud, side panel, number plate, fork guard, and chain slider fasteners.
• Includes extra pieces so quick fixes at the track are possible.
• Shouldered seat bolts replace worn or stripped originals for proper seat alignment.

Are these bolts durable enough for off-road and race use?

Specbolt manufactures these fasteners from 10.9 grade heat-treated alloy steel, offering higher tensile strength than basic mild steel hardware. They’re designed to resist bending and stripping under typical trail and motocross stresses, though final performance depends on correct installation and torque.

• 10.9 grade heat-treated construction for stronger clamping and fatigue resistance.
• OEM-correct lengths and head styles to preserve panel fitment and clearance.
• Includes modern-style components used on newer CRF models.

Which parts of my bike will this kit cover and what extras are included?

The set covers nearly every plastic-mounted fastener on a CRF 150/250/450 four-stroke, supplying the typical hardware to fully reinstall bodywork after service or repair. Extras allow for future replacements without returning to the store.

• Front and rear fender, radiator shrouds, seat bolts, side panels, fork guards.
• Number plates, chain slider, and rear brake line guide fasteners included.
• Several spare bolts and nuts are packed for common future wear points.

Who is this for: Riders, mechanics and track-side support crews working on Honda CRF150R, CRF250R, CRF450R (and applicable CRF-X models) who prefer a single, reliable source for OEM-style plastics fasteners. If you maintain multiple bikes, restore panels after a crash, or want organized spares for race day, this Specbolt 90-piece kit removes the guesswork and keeps your plastics mounted correctly.
