Product Description

Looking for an exhaust system that was extensively engine dyno tested to provide the most power possible? Look no further than our RS1 full exhaust system. Bikeman utilizes a Superflow 902 Engine dyno while designing new products unlike many others that try to measure engine components on wheel dyno alone. Our header went through many stages of development to provide maximum air flow whether you’re running a stock or modified motor. The development of the head pipe section was long and tedious testing all the variables to zero in on what the RS1 engine wanted. This final design utilizes power tuned head pipes to the correct length and shape just for the RS1 1000 motor, a large high strength flex joint with V band connection to the Big Mo muffler. The Header has a high temp ceramic coating. This special coating holds a great amount of heat into the pipe and is meant to withstand the high temperatures of exhaust components. The Big Mo muffler is an ultra high quality piece made from billet aluminum and a precision extrusion. The Big Mo muffler has optional accessories that will tone down the decibels and provide spark arresting. This will slightly tone down the volume and make it legal for areas needing spark arrestors to ride. This exhaust provides great power with exceptional sound that is not obnoxiously loud, but just right. This system is what you need if you are a serious RS1 racing enthusiast.

These graph are a representation of the gain while running BMP Tuner, Exhaust and Stage 2 clutching verses All stock. During the run street tires were used to maintain a consistent grip to the dyno rollers. Horsepower is depicted red being scaled on the left of the page and RPM is depicted Blue being scaled on the right side of page. The baseline stock rpm and horsepower is the darker red and darker blue lines. The stock maximum horsepower was a consistent 82, RPM stayed below 8350 and would not go over 73 mph due to ECU limiters. In the tuning the electronic limitations have been adjusted for maximum performance RPM limits are raised to 9000, Electronic speed limiters are raised to 120 (this eliminates any electronic speed limit), Torque limits are raised (allows for the most acceleration possible), ignition timing and fuel curves are optimized for BMP exhaust, Dual cooling fans are controlled independently (fan 1 will kick on at 185 while fan 2 will kick on at 190 minimizing load on charging system until needed.

Gains are great as you can see by the graphs power comes on faster, makes more and lasts longer! Customers will see about a 20mph gain on top speed as well.
