Yes they are just plastic covers, pretty embarassed when I found out..
Anyway, I just installed risers last night. I found these at my local bike shop:
http://zeta-racing.com/clamps/bar_rise_286/index.htmlThey sit directly in your current handlebar bed then you screw on the top clamp. I used the 30mm, about 1 1/4 inch. I wouldn't go higher than that. The brake cable is pretty tight but the guy at the bike shop said it should be fine. You can turn your handlebars forward to give it a bit of slack, but that pushed your brake and clutch a bit further down but not too much.
I was looking at these
http://shop.sw-motech.com/en/by+products/Ergonomics/Bar+Riser/index.htm e-mailed the company and they told me they won't fit on the fazer..
I'm sure you can find other ones online but I wanted to make sure they fit that's why I bought them at the shop. Plus they were cheaper than any I found online. 49$ Cdn.
Makes a huge difference I should have done this a long time ago.
Cheers
