Bar risers are definitely good.....I fitted mine 'backwards', EG they go up and FORWARDS rather than up and towards me......made a big difference.
Pivot pegs are also good, as they not only lower the pegs, but also allow them to....er....pivot
That means your feet aren't quite as glued in position so you can rotate ankles a bit on the move.
If you wear MX boots though and have feet commensurate with your height, you may also need a gear extender.....I just couldn't fit my size 13 boots under the gear change lever with the wider Pivot pegs on and my Volvo kickers on my feet
Daft but quick idea.......loosen the bars off and twist them up/round a few inches as well......watch for taught cabling and be careful on a test ride 'cos obviously the controls will be shifted as well, but that might give you a feel for a better position you can aim for
PS take the cash-laden brand snobs who instantly say things like 'Get a Corbin, that will '
definitely sort you out' with a bucket of salt......for one thing, one expensive seat is very different from another expensive seat in fit and suitability and you could go through the whole range before you find one that works for you, spending a couple of grand in the process....
For another, they are fucking expensive and relatively cheap and easy solutions, although they may lack the brand cache that so many of the people here seem to worship, often work far better.....treating the cause rather than the symptoms.
