I bought a set of these and had them installed on my F3 in the summer of ‘04. I thought that I’d relate my experience (and should have done so sooner based on my search).
The service from Convertibars was very courteous and my package arrived in a couple of weeks. All the parts are beautifully made and look great. I would not hesitate to deal with Convertibars again. In fact I intend to purchase a second set for my next bike if all goes as planned.
On the Convertibars website you can check the fitment of your particular bike and get an idea about how much higher/farther back your bars can move with the kit. If the columns in this table are filled with TBD (to be determined) then they have not confirmed your bike. This was the case for my bike a 98 CBR 600F3. I was optimistic that they would fit but was quite disappointed that the bars could only be moved up about an inch and back about half an inch. Although on many bikes you can vary the fit significantly, the F3 fits only with faring modification and only in one position give or take 1 cm. This is the first lesson - confirm the fitment of your bike. If the bike doesn’t have a confirmed fit then you are taking a chance. The new bars were more comfortable and I was surprised at how much difference an inch can make in comfort. I still wanted more so I started playing around with the kit myself. To my horror I realized that the mechanic who installed them cut off the excess bar travel. Lesson two - do not cut the bars down unless you are completely satisfied and have no intension of selling the kit in the future. The kit is now limited to about 1" of travel up and down.
This kit is pricey. It would be worth it if it gave me at least 3" up and back but for my setup there are less expensive alternatives. Take a look at the travel difference for a new GSXR 1000 - 5" higher and 6" back... That’s what I’d like! - coffeecat
