The kit also includes 12-volt and 5-volt power adapters for wiring the system into your bike's power supply, and a stereo cable that can be patched into your existing audio system or your helmet.

Sirius Radio To Go

Txwag91 from Oxnard, CA on 8/31/2008

Crutchfield Customer Review (What's this?)

Works Great! Installation was smooth overall. I had to lengthen the power wires so the fuse box would reach under the seat and not the gas tank, but overall installation was pretty easy. I have a Sportster 5 which I switch back and forth between the F-150 and the Harley, so it works out great. Was definitely what I was looking for.



Mount works Great

Crutchfield Customer Review (What's this?)

I have a 2001 Electra Glide Classic and a Sirius Sportster 4. I purchased the Sirius RPMK1 mount kit and I love it. It was easy to install and it worked the way it is supposed to. The lock on the back locks the unit from coming loose. The only thing I wish was different is the mount bracket. It is plastic and the unit vibrates more than I think it would if the bracket were metal. It really is a good product and worth the price.... Thank you Crutchfield for the prompt and friendly service...Glenn



SIRIUS Motorcycle Kit

Ralph from Hernando, FL on 4/5/2007

Crutchfield Customer Review (What's this?)

I purchased a Stratus Radio Unit which was listed as a unit designed to work with Motorcycle KIt. In the motorcycle kit, the docking unit was advertised as having a locking device to secure the radio to the docking unit. There is a slide lock on the rear of the docking unit but it does not secure the radio as advertised. As a matter of fact, the slide lock does not even come in contact with the radio.




Hands-on research

Product Research



Overview: The SIR-PMK1 Pro Motorcycle Kit provides mounting hardware and power connections for the most recent Sportster (SP4), Starmate (ST4), and Stratus (SV3) Sirius plug and play tuner models. The previous generation Sportster (SP3) and  Starmate (ST3) are also compatible, but require using the docking cradle from those tuner's car mounting kits (the included cradle won't work with the older models, but should work with new models going forward).

Mounting: The SIR-PMK1 comes supplied with a cradle compatible with the Sirius Sportster 4, Starmate 4, and Stratus models. Several other Sirius models (listed below) are also compatible, but require use of the cradle included with their respective car mounting kits. The cradle bolts to the included swivel bracket. The swivel bracket is then mounted to the handlebars using the included handlebar clamp. The swivel bracket is also compatible with many clutch and brake handle clamps, so the included clamp may not be necessary. One of the two included antenna brackets is also bolted in place with the swivel bracket.

Moisture Guard: Two moisture guard cases are included; one fits the Sportster series 3 and 4, the other fits the Starmate series 3 and 4 and the Stratus. The case covers the Sirius tuner and cradle once they're mounted.

Audio Integration: There three ways to integrate the Sirius audio into your existing stereo:

  • Line output: use the 3.5mm stereo mini-jack on the cradle to feed the aux input of the stereo or in-helmet headphone system (some high efficiency headphones can be powered without an amp)
  • Built-in FM Modulator: depending on placement, the FM modulator built into the Sirius tuner may transmit wirelessly to the existing stereo
  • FM Direct: the optional FM Direct relay (item number 607FMDA25) can be added for a wired FM modulated connection

Dual Voltage Power Adapter: Even though all the Sirius tuner models the Pro Motorcycle Install Kit is designed for operate on 5.2 volt power supplies, the included adapter has dual voltage outputs. The adapter features the following connections:

  • 2-Pin Connector: use the supplied 5.2 volt cable to power your Sirius tuner
  • 3-Pin Connector: use the supplied 12 volt cable to power your Sirius tuner
  • Power/Ground Leads: Two 16" wire leads used to supply power and ground that will be attached to your vehicle

Additional Semi-Compatibility: In addition to the compatible models listed above, the mounting kit can be used with several other Sirius tuners, both current and older generations. The included cradle may not work and there is no moisture cover for the following Sirius tuners:

  • 12-Volt Series:
    • Sportster: SPR1, SPR1A
    • Sportster Relay: SPR2
    • Starmate: ST1
    • Starmate Replay: ST2
    • Sirius One: SV1
  • 5.2-Volt Series:
