DescriptionThe whole story▼
Nothing on an R1M looks more like an afterthought than the original fluid reservoir. That is what the OBT001 does — 31 cm³ of fluid behind billet aluminium, 106 g on the bike. There are 2 finishes to choose from, all at the same price. It goes onto the R1M without modification and comes off again just as easily.
Key Features
- 2 anodised finishes for the R1M: Gold, Green
- Reversible — the original part goes back on the R1M any time
- Finish changes the look of the R1M, not the fit
- Covers the R1M across 12 model years (2015 to 2026)
- LighTech part number OBT001, listed for the Yamaha R1M
- 106 g on the R1M
In the Workshop
Installation on the R1M needs no special service tool. Use fresh fluid of the grade the R1M specifies, not what is left in the bottle. Re-check the fasteners after the first ride.
Compatibility
This listing covers the Yamaha R1M, 2015 to 2026. It is a universal article in LighTech's own description; the R1M is the application, not the design brief.
The Case for Billet
A fluid reservoir does two things, and the factory part does only one of them. The OBT001 comes with a rubber gasket under the cap, which is what keeps fluid where it belongs. At 106 g it weighs about what the plastic original does.
What Is in the Box
LighTech ships the OBT001 complete except for the mount. Spares are listed under their own numbers rather than bundled.
What You Also Need
A mount is not included with the OBT001. LighTech offers a front bracket (OBT008) and a rear one (OBT009), plus the OBT003 support, and all three are black only. We can advise which of the three suits your R1M — it takes one question.
Maintenance
Change the fluid at the interval the R1M manual gives, not when it looks bad. Beyond that the OBT001 asks nothing of you.
Approval and Safety
The hydraulic circuit is the one area where a styling part stops being a styling part. The OBT001 carries no approval mark. Have a workshop bleed and pressure-test the R1M circuit once the part is on, whatever your inspector says.
