Description
For riders seeking a minimalist aesthetic without compromising safety compliance, these Motone Custom Billet Turn Signals deliver precision engineering in a compact 43mm diameter package. CNC-machined from solid 6061 aluminum and finished in stealth black anodization, each indicator represents the intersection of British custom motorcycle heritage and modern manufacturing technology—providing E-marked legal visibility while eliminating the bulk of OEM plastic housings.
Key Features
CNC-Machined 6061 Billet Aluminum Construction
Turned from solid billet 6061-T6 aluminum alloy using computer-controlled precision machining that ensures perfect concentricity between the lens housing and mounting stem. Unlike cast or stamped indicators prone to porosity and dimensional variation, billet construction provides consistent wall thickness and eliminates internal stress points that cause cracking under vibration. The aluminum body weighs just 42g per unit—reducing unsprung mass compared to 180g+ OEM assemblies.
Type II Black Anodization with Corrosion Resistance
Finished with Type II sulfuric anodization creating a 10-15 micron hardened surface layer that resists scratching, UV degradation, and corrosive exposure to road salt and petroleum products. The matte black finish integrates seamlessly with blacked-out custom builds while providing superior durability compared to powder coating, which chips under impact. Anodization penetrates the aluminum substrate rather than sitting on the surface, ensuring color fastness through years of environmental exposure.
Dual Lens System with E-Mark Certification
Ships with both clear and amber 40mm diameter lenses, allowing customization based on local regulations and personal preference. All lenses carry E-mark certification (European ECE R6 compliance), ensuring legal street use in markets requiring certified lighting equipment. The polycarbonate lens material withstands impact from road debris and resists yellowing from UV exposure better than acrylic alternatives. Lens retention uses internal O-ring sealing to prevent water ingress.
Premium Osram 10W Amber Bulb Package
Equipped with genuine Osram 12V/10W amber bulbs engineered for high-vibration motorcycle applications. Osram’s dual-contact bayonet base design ensures positive electrical connection under sustained vibration, while the amber glass envelope provides inherent color filtration (2200K color temperature) for enhanced visibility in daylight conditions. The 10W output meets brightness requirements for both daytime running and nighttime signaling across most jurisdictions.
Stainless Steel Mounting Stem with Universal Fitment
Features a 10mm diameter stainless steel 303 mounting stem turned on CNC lathes for precision threading, with 30mm of usable threaded length accommodating mounting brackets from 2mm to 25mm thickness. The stainless construction resists thread galling and corrosion at the mounting interface—a critical durability factor where aluminum stems fail under overtightening. Standard 10mm threading ensures compatibility with virtually all aftermarket indicator brackets and OEM mounting points.

Installation Note: These indicators use universal bullet-type electrical connectors and do not plug directly into Triumph Twin OEM wiring looms (both air-cooled and liquid-cooled models). Electrical adapters are required for plug-and-play installation—verify your motorcycle’s connector type before purchase. For mounting, torque the 10mm stainless stem to 8-10 Nm maximum to prevent thread damage. Always test indicator flash rate after installation, as low-wattage LED or reduced bulb count may require load resistors or flasher relay replacement to prevent hyper-flashing.
