You loved our RSL-01, and RSL-02 models of this clock. Now the newest RSL-03 model is available and for the first time, with matching thermometers! We made a couple subtle changes to the RSL-03 model line: The sweep hand is now Formotion red, and the new ** RSL-03 thermometers are designed and engineered to not need oil encapsulation for ease of maintenance and long-lasting display. You can also order a separate stick-on (smooth style) back - $5 - with fitted O-ring and pre-attached 3M VHB tape that allows you to change out the case back from its standard “stem” back (bolt-on) configuration to a smooth back that allows for tape or Velcro mounting to a flat surface instead. - so, you'll be able to mount the RSL-03 anywhere. and in any way you like!

**NOTE: Because the RSL line uses “air filled” (no internal dampening) thermometers vs our Signature Series “oil filled” (internal oil dampening) thermometers, strong vibration, like that that can be found on some single cylinder engines, as well as some twin engine brands like Triumphs, KTM’s et al it is recomended in these intense vibration situations to use our oil filled Signature Series thermometers for trusted results. RSL Clocks in these situations pose no issue.

Bolt-On allows for unlimited mounting options. Comes with all mounting hardware to attach to any 1/4” screw or bolt. Optional handlebar mounts sold separately.

Optional “smooth” case back is available to convert the RSL-03 to a stick-on type for flat surface mounting.
