"It feels like I have 3 different exhausts."

“Dust, mud, extreme weather ... I ride a BMW GS as it is meant to be! A motorcycle that breathes adventure must occasionally go off the paved road and offroad! “I used to drive with an exhaust that had only one mode, which means that there was only one sound. This was not really contributing to the driving experience. Driving with a closed valve on the paved road and opening the valve off-road really adds an extra dimension to the driving experience; it feels like I have 3 different exhausts! It is a great concept: if you show it to other people, you get a lot of positive feedback."

"A clear plus for safety!”
Werner - Berrt Travel  |   BMW GS

"Mr. Hyde position (valve open) is also ideal if I am quietly riding through traffic jams. The heavier sound is more noticeable and combined with a small speed difference it has a huge effect on the reaction of cars and trucks. A clear plus for safety!”

"The Exhaust gives you a real fighting mentality."
Xavier  |   BMW GS

“The Mr. Hyde mode allows me to communicate better with my motorcycle. Due to the different sound modes you get more feedback from your motorcycle, which helps, among other things, to signal when something is wrong with the motorcycle. For example when the tires have to be replaced. Mr. Hyde mode really wakes you up during a long drive or when I go off-road; it activates and motivates you. It gives you a real fighting mentality."

"...this button that turns beauty into a beast!"
Peter Janczik  |   BMW GS

"The name really says it all: Dr. Jekill & Mr. Hyde! Apart from the great workmanship and the fantastic quality, it rounds off the entire look of my R1250GS Adventure TripleBlack perfectly. Then there is this button that turns beauty into a beast! What really impressed me is the possibility to be even quieter than a series with it. And every now and then there is this itch in the left thumb, with the subsequent grin on the face. "

"Perfect for off road rides or near residential areas."
Nikki van der Spek - GS Trophy participant 2020  |   BMW GS

"When you close the valve then the exhaust is quiet but sounds very smooth. Perfect for off road rides in nature or near residential areas. But when you open the valve and open the throttle, then the GS has a beautiful sound. Loud but not too loud, just perfect. It has a nice and dark sound."

"Ride in stealth mode and not disturb anyone."
Jean - GS enthousiast  |   BMW GS

“I love to ride along the shores of Gérardmer Lake (Vosges, France). A beautiful place full of walkers, cyclists and sports enthusiasts. When I drive here I always use the Dr. Jekill mode, which gives me the possibility to ride in stealth mode and not disturb anyone. But when I make my way back on the meandering roads of Col de Bonnefontaine I switch to the Mr. Hyde mode to enjoy the delicious rumble that echoes through the mountains around me and at the same time warn oncoming traffic that I am approaching. Great right?”
