My local BMW dealer fitted my Protaper bar today. I used a riser / 22 to 28mm adapter, similar to ROX.
We used the 310 Barkbusters which I had on, and to make them fit they did the following: a thread inset into the open bar end of the Protaper, like the one the OEM bar have.
Then they fitted the BB, using the bar weights. They had to drill the hole bigger, to be the same as the threat inset. The 310 BB bar C-clamp doesn't fit over the thicker bar, so they used spacers as a temporary solution until I can get the 28mm fitting. The didn't had round head screws, so I will just later replace the ones that they used.
On the 10 km ride back home I immediately felt the following:
- Less vibration on the mirrors
- I had a better angle of view in the mirrors. With the OEM my elbows were covering half the view. Think it is due to the bars maybe a little more forward, and or wider, so my arms were more straight.
- The setup is for me, 1,8 m tall, perfect, seated and standing. I think the risers lift the bar somewhere between 22 and 30 mm.
The bar, risers, threat insert and fitment cost me $180, which is not bad. I still have to add the new BB 28 mm C-clamps to the cost.
