I crashed my bike in Northern Alberta in the Mountains on a trip to Alaska, and the cylinder head plastic covers were severely damaged, and the OEM crash bar was bent. I think these re-enforcement bars are a mandatory as are the cylinder had guards/protectors. I purchased the BMW OEM cylinder head guards/protectors and the Touratech re-enforcement bars. I should not have to worry in the future about damage to the cylinder heads and engine.
If you don't have a product listed on your website, it should be listed as out of stock or back order. Once I placed the order, a reply telling me the air filter was out of stock and anticipated shipment date would have been helpful. I ordered and waited 3 days on some kind of notification. Crickets. I emailed to inquire. Crickets. Finally called to find out that you had to order the filter.
