The M109R is one of the most powerful V-twin cruisers on the market. We have found a way to give it even more power with the BigAir kit The kit comes in powder coated black or chromed and has produced some of the best hp numbers that we have seen to date . The kit is an adaptor that will bolt on to the back portion of your stock air box. With Cobra Speedster pipes, and a Power Commander map we are putting 122.5 hp to the rear wheel and 116.6 ft. lbs of torque
