This rear shock has greatly impressed me over the last 500 miles I've put on my Falcon Pro. The BDA53RC that comes on the bike had a 450lb spring and it was too light so I got a big upgrade with the 550lb RAB53RV.
I ride solely street and my bike went from a stiff uncomfortable ride to an absolute dream soft ride. The low/high speed compression and rebound can be adjusted to the point where any bump in the road or curb can be completely negated and that's all I could of asked for. A+ best shock for the money on the market
