Hi Mihalis! I haven't been able to ride much but I did manage to get about 80 miles in with the MV riser plate installed. It moves the bars back a little more than the Heli risers which is good for me.. The bars are very adjustable. I adjusted them by holding my hands over the bars and matching the angle of my hands. Usually after about 20 minutes my right hand would begin to ache but after nearly 2 hours my right hand felt fine. Bear in mind I've never ridden this bike with the stock bar position. It had Heli risers on it when I bought it. The MV Motorrad riser is an improvement over the Heli risers in my opinion. I think you should buy one and put it on your gen1, you won't be disappointed.
I need to make a correction to my previous post regarding missing hardware. When I installed the riser I was quite medicated with muscle relaxers and pain killers due to a very painful back condition and was tired of TV and wanted to improve my bike, even if I couldn't ride it. I posted that MV had not provided all the necessary bolts to install the riser. Well...... a couple weeks after I bolted it on I was disposing of the box and packing material it was shipped in and there were the bolts buried in the paper packing. Doh!
My apologies to MV Motorrad. They produce a fine product and they include the hardware.
