[350TSS]

The race supplies rearsets are good value for money - but for a road bike they have 2 downsides, first is that they are quite high, absolutely suitable for Desmodue racing where you are only on the bike for 15 minutes and need the ground clearance but not really suitable for more than 30 minutes as the knee and ankle joints are at acute angles, secondly they do not have provision for a brake light switch which can be overcome with a hydraulc pressure switch available from ebay at less than a tenner.
Their fit to the frame also means that they are much narrower than the standard pegs, which also helps with ground clearance but can cause issues with clearance on the exhaust and/or side stand/ gear shift rod.
Narrower footrests are in my view a good thing as the standard Monster has footrest positions quite a bit wider than the normal human pelvic / hip joint width and if the joint is forced to bear load when the the femurs are splayed it will not be as comfortable or as strong as when the force is in line with the hip joint.
The standard footrest position for a Monster is actually very good ergonomically, fore and aft relative to the SA pivot and vertically relative to the height of the seat, both for comfort and for balance/weight transfer. Moving the footrests inboard by 25mm each side but maintaining their relative fore and aft and vertical position relative to the SA spindle gives the best compromise between comfort for an extended duration, ability to move around on the bike, weighting the pegs to assist indirection changes and ground clearance
