I’ve tried just about every option out there, Monkeys grips are 2nd place for best ergonomics, but the hands down winner by a wide margin is the RADE Garage setup for track, the tank shape is perfect and you get the wider seat all in one clean neat package. It’s actually so good that it takes some adjusting to. Because it fundamentally solves all the seat and tank ergo deficiencies of our bikes by complete redesign of it.
It’s about like the Aprillia RSV4 and Kramer GP2 but with a wider seat.
