I have a beta rev 3 that I use for trail riding. I fitted 2" rox risers set up to move the bars up about an 1" and forward about 1". It makes a very big difference to how long I can ride for (previously my lower back and hands would be killing me after 4 hrs or so riding). These risers are are the rubber mounted ones made for ATV's and work really well at dampening out the Betas high rev buzz on transport sections.
As a further heresy I'm considering fitting pivot pegs as they are so comfortable to stand on on my trail bike and adv bike - I'm sure that will get a few eye rolls as well from the purists.
