Limit RPM's and cost would go down dramatically. IMHO.

Yes, please email me and I'll explain your options and Vital discount. The new style SX450 system was developed with the help of PJ Larsen. He's an excellent test rider. His feedback combined with our dyno resulted in a very good system. We managed to ... more »

Cygnus, I really appreciate the kind words! For the record our bikes, engines and exhausts (spelled correctly) are world class and have many advantages over the big boys. Expect good power and just as important our exhausts are better priced, more durable,

That's right Rock. There are 9 different throttle positions and most riders spend very little time at 100% open. 3-5% of the time from data I have seen. The dyno is one tool.

The motor design is a awesome. Our stage 3 mod with piston, cams, throttle body mod, valve springs and our exhaust is making 47.5 on our dyno. Stock is 40.8. As another reference most 250 mods you can buy are in the 44-45 range. The cylinder head design ... more »

Comparable PC T-6 system retails for $809.85. My Race system with a Carbon end cap, an option PC does not offer, retails for $577.45. With the weekend 30% discount $404.15. There is more value with our pipes. Besides the carbon end cap, it is much easier

We run modified 50mm throttle bodies and a proprietary injector. CNC ported head and combustion chamber, our own cam and valves and a Cosworth piston. We have Stage 1,2 and 3 engine kits available rices from over $1000 to $12,000.

Great question. There is soo much fine tuning that can be done with mapping. There are 9 different throttle positions and with the Vortex ECU's we use and you can adjust air fuel ratio every 250 RPM's. Spending the time to do this on each individual ... more »

The cylinder head intake port design of the 14 YZ250F is the key. Both ports are the same length and there is no bends. The air/fuel flow has a straight shot and disperses evenly across each valve. Average mod hp for the traditional cylinder heads of
