Hi fellow V11 riders,
I’m diving into a custom fabrication project for my Moto Guzzi V11 Le Mans—specifically around engine side covers and fairing repair using acrylic or ABS plastics. Thought I’d open a discussion here to share what I’ve tried and learn from others working on similar mods.
Project Background:
Right side engine cover has a cracked section from a tip-over.
Left fairing intake trim had a missing insert.
I plan to fabricate replacement parts using either ABS or 2 mm acrylic, shaped to match OEM contours.
Current Setup:
CAD sketches based on molds and photos.
Prototype parts cut on a CNC router or laser based on the material.
Sanding and smoothing by hand before finishing.
Questions I’m working through:
Material suitability: Is ABS sheet stronger and more heat-resistant around the engine versus acrylic?
CNC vs heat forming: Best practice for cutting complex curves—do people prefer pre-shaping acrylic via heat bend or go straight to CNC routing?
Mounting method: How are you bonding your fabricated parts? I plan to use high-temp epoxy or solvent welding, but curious about vibration and durability on engine vibration zones.
Paint prep: For panels near heat or vibration—how do you prep fabricated plastic to match OEM finish and hold up in the elements?
Would love to hear input from anyone who’s fabricated or repaired V11 parts—or has experience with custom motorcycle plastics more broadly. If you're using a blend of fabrication methods or have photos of past repairs, I’d be excited to see!
Looking forward to your ideas.
