Hey, yes these are from CounterShox. the blue one on the fork is straight off the moto bike. I tested on my Yamaha 450 first and then had to try on DH bike. I knew it would have a bigger effect. The mount is off a 85cc dirt bike, they have the same diameter clamp as dorado. The one mounted to the seattube is lighter, about 1lb. I 3D printed a mount so it doesn’t rub again the frame. These TMD are not adjustable, from talking to the folks at CounterShox, they have put so much R&D into weights, springs...
