[31/01/2015 @ 3,700km] – Installed oil cooler guard from Wunderlich today. Liked the wrap around the radiator on both sides. Others are just plain grill design. Held on by 2 bolts at the rear, it is much better than those which uses zip ties found on GS. After a year or so, they harden and become brittle.
Comes with self adhesive tape to minimize rubbing to the radiator but I’d rather leave a gap and not allow the guard to touch the radiator. Not good when there are lots of vibration and the radiator is made from softer aluminium than the guard.
Since I am at the radiator, I thought I’d remove both front indicator light extensions. The indicators now bolted directly to the radiator and is narrower by one inch on each side.
Just a thought, cleaning and removing crap from the radiator might be harder now since there is some distance in between the guard and the radiator. Maybe a paint brush will help.
Note: May also fit the oil cooler radiators for S1000R and RR. There are instructions for both bikes also included. More details here: http://www.wunderlich.de/shop/en/bmw-r-serie/ninet/rundumschutz/olk-hlerschutzgitter.html.
