TRX850 2-1 large bore stainless steel race system

This is our large bore full stainless steel race system for the TRX850. The system is a 2-1 with a right side exit, meaning that you only need to use one silencer- saving the weight of one hanger, link pipe and silencer over the standard 2-2 system. The headers are 1.75" (44.4mm) o/d 16swg and the rest of the system comprises 2" o/d 18swg tubing.

The link pipes will allow you to fit any universal 2" (50mm) bore race pipe so you aren't limited by what we can supply, you can use any silencer you like with our pipes. A silencer is not included- the system comprises headers, 2-1 collector and link pipe.

They are designed around a standard bike but will fit around a wider Thunderace or YZF750 swingarm and there is a degree of flexibility built-in as the systems are held together with springs, not clamps.

The system is rebuildable and extra or replacement parts can be ordered at any time.

The dyno chart shows a run done with the standard headers fitted and our system. Our system helped the engine produce an extra 8.5bhp (nearly 12 percent!) with more torque everywhere. The bike had the standard carbs fitted.

This would make an excellent addition to a bike already running FCRs.

Please note- these systems are made to order and turnaround is between 7-10 working days.
