Shipping was insanely fast, specially considering I ordered it on a Friday of a holiday weekend and still got it within 4 days from the other side of the country. Quality looks to be good.

Nice upgrade

The look and feel is nice and the fact you can adjusted the levers are nice too. The only reason not 5 stars, I feel like the brake lever is a little looser than the OEM, but maybe that by designs because I’ve read other say tue same. Nice product and would buy again.

Kawasaki Vulcan S 650 testosterone shot.

I actually put this on a Kawasaki Vulcan S 650. Doing this solves the exaggerated nose diving when getting off the throttle. Definitely gets the Vulcan S to the 6k rpm range sooner, where the 650 actually wakes up. Great alternative to going the " booster plug" route. Much cheaper and simpler too.
