A BSD record-breaker; this beautiful 2011 Suzuki GSX-R750, running a full Arrow exhaust left the workshop making a full 140 genuine bhp at the back wheel. We fitted the Power Commander PC V and trimmed it up on the Dyno – Arrow systems tend to be built to deliver a strong top-end at the expense of bottom and mid-range power, and in this case fuel needed taking out through 5,6,7,8,000rpm to help the engine burn more efficiently and sharpen up the power delivery for road use.
