I added a 16 tooth front sprocket to my GSXR 1000 yesterday and already had two up on the rear. What a kick ass wheelie machine! I had a grin on my face like a wave on a slop bucket! It's raining today but can't wait for the next dry day. These lower gears just made doing wheelies so effortless. Stand up wheelies in second gear with just a twist of the throttle is so effortless. And, it reduced the speed when doing wheelies in third gear, where I do my best wheelies. Have to be a little bit careful in low gear. It comes up so quick it will be easy to over throttle it. I have three up on the rear of my busa and thinking about trying a 16 on the front just for kicks?
