I researched bar risers for my 2010 RT, and here's my summary by vendor including cost and change in handlebar position. Most of these descriptions are from the vendors literature. From what I've seen from other postings, many of these bar risers work fine. Cost does not seem to be a factor, i.e., more $ is not necessarily better.
ps.
Some of these data/costs may be old from 2010 when I started compiling this list.
Wunderlich $119
- 25mm taller (0.984”).
Ilium $89.95
- Up .898" and back 1.032" for a total diagonal movement of 1.375". Stresses brake line.
- Part #11-600 ($149.95) bar backs for 2010-11 include extended front brake line and mounting manifold.
Suburban Machinery $99.95
- Net change .894” up, .447” back. No change to brake line.
Moto-Techniques $69.95
Moves bars up & back diagonally ~1" to unload weight from wrists & forearms and relax the neck. Uses stock control cables and requires no modifications. New bolts are supplied.
Vario Handlebar risers $235
- Allows a wide range of adjustment: The base position has the handlebars 30 mm (1.18”) higher than standard. Then the step-less adjustment allows them to be moved back toward the rider by up to 20 mm (0.78”). Additionally, each handle bar can be moved outwards by up to 25 mm (1”) from standard. This results in massive 50 mm (2”) overall increase in handlebar width for a true “touring” feeling.
Heli Bars $119
- Raise them 1" (25mm) and move them towards the rider 1" (25mm).
Touratech $129
- Raise the handlebar by approximately 20 mm (~.8”).
CVM Touring $75
- Bar Backs move handlebars 1 inch up, and 1 inch closer to rider.
Verholen R1200RT Adjustable Handlebar Risers (from Creative Cycle Concepts) $330
- With other risers, you've been able to move your handlebars up and back. Now ONLY from Verholen, not only do you get 25mm up, and 35 mm back, you also get handlebars that PIVOT on the Vario Handlebar Plate, by up to 15 degrees for each handlebar. That's a 1.7 inch diagonal rise , PLUS adjustable pivoting mounting plates that move your hand grips further away from the bike. Not only do you get relief for your neck shoulders and back, but you also get more elbow room and relief for your wrists.
I have the Verholen and have been happy with them except for the price. Please note that the handlebars only tilt AWAY from you from the standard stock position.
Good luck.
