The side of the GS definitely deserves side covers.
The unsightly hole in the frame is not really optically attractive and it does not protect against dirt and splashing water, which is whirled from the rear wheel and lands on the driver's and passenger's trousers.
Thanks to Wunderlich's side covers, these deficits are eliminated within seconds.
The facts:

• Homogeneous, slim and precisely fitted shape
• Safe attachment options
• Easy mounting
• Whirled dirt is significantly diminished
• High quality and ultra light-weight ABS hard plastic
• Scratch proof and very stable
• Black colour
• Delivery inclusive complete fitting kit
• TÜV approval not necessary
