Nightrider is proud to introduce the AF-XIED for BMW to its product line. After extensive development and testing, we have adapted the most sophisticated version of our Patented narrowband O2 sensor inline enrichment technology for use with the BMW Motronics 2.x series and BMSK ECM's used in the R1100, R1150, R1200, K-Series and F800 motorcycles.

This technology allows the BMW AF-XIED to provide the most accurate control over narrow band O2 sensors achievable, allowing very accurate Lambda shifts from the emissions mandated 1.000 (14.7:1 AFR) to 0.939 (13.8:1) normally only seen by wide band sensor upgrades. Stable mixtures of Lambda 0.925 (13.6:1) have been seen in some bikes. All of this in a low-cost, simple, plug-n-play package that can be installed with a minimal of effort.

The BMW AF-XIED is available for R1150, R1200, K-series and F800 model bikes. These bikes have custom designed plug-n-play harness adapters that allow a Rider to easily plug the BMW AF-XIED into their bikes wiring harness with no additional modifications. Using OEM style connectors, installation has been simplified. This installation does not even require connecting a wire to the battery.

The R1100 is supported with our R1100HA single cut adapter cable, allowing installation of the BMW AF-XIED with a minimum of disruption to the OEM wiring harness.

Nightrider also has a Universal Harness designed for any 4-wire heated O2 sensor (Lambda Probe). With the universal harness, you can wire into any OEM wiring harness or crimp your own OEM connectors to the BMW AF-XIED.

Additional motorcycles supported by the BMW AF-XIED include Husqvarna and Indian. The Husqvarna uses the R1200 style Harness Adapter. There is a new plug-n-play Harness Adapter available for all 2014>later Indian motorcycle models, including Chief and Scout.

Bmw k1100
I purchased this unit for my early 93 BMW k1100 to control a heat issue that seams to plague these bikes. First of all the install is very easy and straight forward although the instructions have you tapping into the 4th wire and it is the 3 wire. My bike is set up with an aftermarket header and a K&N air filter so your application setting may be different than mine. Everything that this product promises it delivers. Quicker throttle response, more mid range and slightly lower engine temps. I have mine set on 5 but as I said you may find another setting that your bike likes better. Did it cure my heat issue? NO but it did help and it sure is fun having a little extra juice on hand.
