DescriptionThe whole story▼
Ordering a lever guard for an R1 without its adapter means it stays in the box. LighTech machines the KPL311 to sit in the R1 bar without play. It costs a fraction of the lever it protects on the R1.
Key Features
- A stock LighTech item, not a special order
- Tightens from inside the R1 bar, so nothing shows on the outside
- Compatible with the LighTech guards ISS113RA, ISS114LA, ISS115RC, ISS116LC, ISS119LA, ISS120RA, ISS200RT, ISS201LT
- LighTech part number KPL311 — the adapter for the Yamaha R1
- Replaces nothing on the R1 — it goes where the bar end is hollow
- Cheapest line on the order and the one that decides whether it works
What You Get
The KPL311 arrives as a single adapter with its M6 screw. Adapters are model-specific; this one is listed for the R1. The KPL311 number is the only thing to quote for a repeat order.
Handlebars Are Not Standard
Handlebar internal diameters are not standard across manufacturers. The KPL311 takes an M6 screw and tightens against the bar from the inside. One adapter per side, so a full set on the R1 means two.
Compatibility and Installation
Catalogued by LighTech for the R1 and nothing else in this listing. Mounting uses the standard bar of the R1; nothing is drilled.
Installation
Installation on the R1 starts with removing the bar-end weight. Thread the KPL311 into the bar, tighten the M6 screw to the figure in the instructions, then check it holds under hand load. On the R1 nothing is drilled and nothing is cut.
Road Approval and Regulations
No series we know of requires a clutch lever guard on an R1. No approval document comes with the KPL311. On a road-registered R1 the fitted position is a matter for your inspection body.
