Description
For Triumph twin riders who understand that engine aesthetics are just as critical as performance, this Motone Finned Timing Cover transforms your motor from factory-functional to custom-crafted. Inspired by the iconic Webco and Magnusson (MPD) designs of vintage racing legends, these precision-cast cooling fins don’t just look period-correct—they actively dissipate heat while protecting your timing components from road debris and minor impacts.
Key Features
High-Pressure Die-Cast Aluminum Construction
Unlike stamped or CNC-machined alternatives, high-pressure die-casting produces a lightweight yet rigid cover with complex fin geometry that maximizes surface area for optimal heat dissipation. The aluminum alloy composition resists corrosion while maintaining structural integrity under thermal cycling from 20°C ambient to 90°C+ operating temperatures. This manufacturing process ensures consistent wall thickness and eliminates weak points common in welded assemblies.
Webco-Inspired Classic Finned Design
Deep horizontal cooling fins replicate the aesthetic of 1960s-70s performance builds while serving a functional purpose—increasing surface area by approximately 40% compared to stock covers, improving thermal radiation efficiency during stop-and-go traffic or track sessions. The black powder-coated finish provides UV resistance and a stealth appearance that complements both traditional and modern Triumph builds.
Complete Gasket and Hardware Kit Included
Every cover ships with a fresh OEM-spec gasket to ensure oil-tight sealing and a retaining clip for internal wiring management, eliminating the need to source additional components. The gasket material withstands modern synthetic oils and maintains compression integrity through hundreds of heat cycles, preventing weeping that plagues reused seals.
Service-Friendly Installation Design
Engineered to accept both stock ACG (“Points”) covers and Motone aftermarket versions without modification. Installation can be completed without draining engine oil if the motorcycle is leaned completely onto its side stand—a time-saving feature for workshops and DIY mechanics alike. Standard M6 bolt pattern ensures compatibility with OEM fasteners.
Wide Triumph Twin Compatibility
Fits all liquid-cooled 900cc and 1200cc Triumph twin engines from 2016 onwards, including Street Twin, Street Scrambler, Bonneville T100, T120, and early Bobber models. This broad compatibility makes it ideal for custom builders working across multiple platforms, though specific exclusions apply for models with redesigned stator systems (see technical specifications below).

Installation Note: Verify your model year and variant before purchase—Euro5 emissions-compliant Speed Twins and 2020+ Scrambler 1200 models feature redesigned stator systems incompatible with this cover. For oil-free installation, lean motorcycle fully onto side stand (left side down) and allow 2-3 minutes for residual oil to drain away from timing cover area before removal.
