Shift light (gear shift indicator)

Two different signals share the name. A shift light says the engine has reached the revs set for changing up (Yamaha, Triumph, Bajaj). An upshift recommendation says a higher gear would save fuel (BMW, Royal Enfield). Neither is a fault.

Check your bike's manual — makers differ.

How urgent is it? What each maker says

  • Blinking, then steady: Information only. Bajaj (Dominar 250): After the first 2,000 km, “RPM limit indicator blinks @ 9200 to 9500 RPM” and “continuously glows” above 9500 RPM; in the running-in period it blinks at 6700 to 7000 RPM.
  • Tachometer turns orange: Information only. Triumph (Tiger 1200): “The gear shift indicator changes the tachometer color to orange when the specified engine speed threshold is reached, indicating to change gear.” The rider can set or disable it; reset is 9,500 rpm.
  • Gear digit flashing: Information only. Yamaha (MT-09, 2021): “When the engine r/min … are in the specified range, the gear indicator will flash.” The start point can be set between 6,000 and 12,800 r/min.
  • Up arrow next to the gear: Information only. Royal Enfield (Himalayan 450): “The gear upshift indicator is a feature advising the rider to upshift the gear for attaining better fuel efficiency.”
  • Upshift recommendation shown: Information only. BMW Motorrad (R 1250 GS Adventure): It “indicates the best time for an upshift from an economical perspective”.

What it is for

Riders use the rev-point kind to change up at the top of the power without watching the rev counter, and the economy kind to save fuel. On the Bajaj Dominar 250 and the Triumph Tiger 1200 the rev point is lower while the engine is being run in.

These pages report what each maker’s owner’s manual says, and quote it wherever safety is involved. They are not a diagnosis and add no riding advice of our own; your own bike’s manual is the authority for your model.

What it looks like
A flashing lamp, a flashing gear digit or a rev counter that changes colour when the engine reaches a set speed; or a small up arrow next to the gear display suggesting a higher gear.
Colour
Orange on the Bajaj Dominar 250 (“RPM Limit LED-ORANGE”); Triumph’s Tiger 1200 turns the tachometer orange. The Yamaha MT-09 flashes the gear display instead of a separate lamp.
Names makers use
Shift indicator (Yamaha); Gear shift indicator (Triumph); Engine RPM limit indicator (Bajaj); Upshift recommendation (BMW Motorrad); Gear upshift indicator (Royal Enfield)

Where makes differ

The rev-point lamps can be set by the rider on the Yamaha MT-09 (a start and stop point in 200 r/min steps) and the Triumph Tiger 1200 (a user-defined threshold); Bajaj fixes its points and changes them after 2,000 km. The economy arrows on the BMW R 1250 GS Adventure and the Royal Enfield Himalayan 450 are worked out by the bike from gear, revs and throttle and are not a rev limit.

What it does not mean

It is not the red line and does not mean the engine is over-revving or damaged; Yamaha’s MT-09 manual gives the tachometer red zone (10,600 r/min and above) separately.

No standard we could read defines these motorcycle lamps — UN Regulation No. 60 and ISO 2575 cover motorcycle tell-tales, but neither could be read when we checked, so this meaning is taken from 5 makers’ own manuals and support pages, each fetched and read on the date shown:
