You know exactly what to expect from Akrapovic, and they do not disappoint. The sound and looks are right on point. Easy to install, with being reafy to ride in under 30 minutes.
Purchasing from SIERRA BMW couldn't have been easier. A top notch company.
Product seems to be well built. Was impressed with the heaviness of the tubing as far as material thickness. Installation was not too difficult after watching the installation videos. Note :There is a later video pertaining to a R1250 RT which showed removing the fan exit air duct from the side panel which was extremely helpful with reassembling of the side panel.
The BMW Motorrad Battery Charger Plus works well once you figure out the plug-in sequence to get the CAN-BUS plug to recognize it. It has a simple display. I have the Oprimat 4 Quad, and while it works well, I always questioned the flashing lights on the display, feeling like I had to figure out what was going on.
