As a longtime Bonneville rider (in my 60s and with 175,000 miles on my 69 T120R) , I am the rider the new T120 was aimed at. I bought mine in 2016 and was impressed with it's comfort and torque, but a little underwhelmed with it's handling. The bike was rock steady but the steering feel when pushed hard in the twisties was vague and uninspiring and I couldn't put my finger on why. Then I noticed the bar risers had quite a bit of pullback that placed the bars a ways away from the steering axis. Aha, I thought. From my backround in bicycling I remembered how a long stem which places the bars away from the steering axis slows steering and makes it vague. It's called the "tiller effect" (look it up online).I found the BC clamp, and from the pictures surmised that they would put the bars in line with the steering axis. I installed them this morning took a ride to attack my favorite set of twisties. Voila! The bike was transformed! Quicker turn in and and almost telepathic feel to the front end compared to stock. These are a true performance upgrade and what the T120 should have had from the factory! Highly recommended. I found myse laughing in my helmet and thinking "now it's a Bonneville"!

nice product looks great, but would have been nice to know you dont need the original top washers when installing this, even the youtube video gets it wrong

Just perfect!

They are highly recommended, I have mounted them on my Street Twin without the height supplement and they are perfect! The handlebar slightly reduces its height which makes it better maneuverability in curves, they are very nice and elegant.
