Tires OEM BMW or MRF

I have these on my Speed 400. I must say they are pretty good. No comparison to any other road tyre MRF has manufactured so far. They are atleast as good as Apollos if not better.

I recommend mrf zlx for sheer comfort and long life

For better handling and winter traction, I would consider getting wider tires.

HD thrust arms are an improvement without too much sacrifice. Better shocks as well. I’ve found tires make a huge difference with the E39.

Narrow, low-profile tires aren't as forgiving over potholes, especially when riding on the 20" wheels.

+1 used those on my e90 BMW last year during the 'record' snowfall and the were great.

Won’t buy MRFs though because they will absolutely get you killed if you push the bike a little bit more than average.

The run flat tires are terrible. They feel like they are made of concrete and the grip is very lacking.
