ro Circuit is famous for its outstanding exhaust systems. Everyone knows that when it comes to racing exhaust systems for 2-strokes, 4-strokes, motorcycles and ATVs, Pro Circuit is one of the best and has won more Championships than almost anyone else.
     For 2007 Pro Circuit has added the much anticipated CRF150R Ti-4 GP Exhaust System to their line-up. This full race system is designed to increase performance from bottom to top end. Full Titanium (silencer and header) construction offers an incredible weight savings when compared to the stock OEM system. And if noise is an issue, don’t worry, the Ti-4 exhaust complies with all the new AMA sound restrictions. The Pro Circuit Ti-4 exhaust systems were developed in conjunction with riders like Ricky Carmichael, James Stewart and Ryan Villopoto, making it the most sought after full race exhaust system in the history of motocross. Suggested retail price is $749.95.
     Pro Circuit also offers the all new CRF150R T-4 GP stainless system, which is now in stock. Styled after their championship winning Ti-4 GP, the T-4 GP offers all the same great performance without the expense of titanium. Suggested retail is $649.95. Plus, Pro Circuit offers slip-on silencers, which increase performance when compared to the OEM silencer. The slip-ons were designed to use the OEM header. The T-4 stainless slip-on silencer retails for $349.95 and the Ti-4 (titanium) slip-on silencer retails for $449.95.
Prepping a new CRF150R for the track requires that “works-bike” vibe that can sometimes only come from adding some trick parts. You can give your new CRF150R that “works bike” look with a Pro Circuit CNC machined billet aluminum brake pedal. Designed to be as good looking as it is functional, this billet brake pedal is more durable than the OEM unit and offers increased feel, superior strength and durability, and includes the cool vibe at a suggested retail price of $149.95.
     Pro Circuit has much more to offer for your customers’ performance needs for the CRF150R and almost any other race bike. A good example is the Pro Circuit Engine Plug Kit. You can add some class and style to your motorcycle with these engine plug kits, which are machined from aircraft grade aluminum for a product that is light, durable and ultra-trick looking. Each piece is hand polished and red anodized for a true “works” looking finish. Pro Circuit Engine Plug Kits will not add any horsepower to your race bike, but they will make you the envy of your local racetrack. Engine Plug Kits are available for most Yamaha, Honda, Kawasaki and Suzuki off-road models with a suggested retail starting a $69.95.
     Other great performance products include the Pro Circuit Clutch Perch. The quick adjusting clutch perch features a threaded on the fly mechanism for precise one-handed clutch cable adjustment. A molded rubber cover wards off debris. The large clamp has a Teflon bushing that enables the lever to twist on the bar instead of breaking off during a fall. The Pro Circuit Clutch Perch assembles easily with all stock levers. Suggested retail is $149.95.
     To improve your bike’s handling, consider a Pro Circuit Linkage System. The Pro Circuit CNC machined linkage system provides better overall stability of the bike during acceleration and deceleration bumps. These are made from T-7075 aluminum and anodized a champagne color. The linkage system includes all linkage bearings. This linkage has a weight savings of over 50% versus the stock system. Suggested retail is $439.95.
     Clutch fade is always a problem with performance machines, so Pro Circuit offers high performance clutch springs. Due to the constant heat and torque abuse the clutch is subjected to, the Pro Circuit designed clutch springs were created to help eliminate clutch slipping and maximize clutch life. Suggested retail is $54.95.
     To help eliminate “sticky throttle” Pro Circuit created the Pro Circuit Throttle Tube. Made from CNC machined aluminum and Teflon coated, the Pro Circuit Throttle Tube is stronger and more durable than the OEM plastic units. With a knurled surface for increased grip and one-piece construction, the Pro Circuit Throttle Tube is far stronger than the OEM plastic unit and the Teflon coating helps ease throttle stick. Suggested retail is $49.95.
     Another trick item is the Pro Circuit Billet Axle Blocks: CNC machined from billet aluminum for strength and light weight these new axle blocks aid in rear wheel alignment, which improves high speed stability and extends chain and sprocket life. Honda axle blocks are anodized red and retail for $49.95.
     A product most of the pros use is the Pro Circuit Launch Control. This is the same launch control that many factory teams use. Engineered exclusively for the unique demands of motocross, GNCC, Supercross, and other starting lines, this product helps riders get the holeshot. The Pro Circuit Launch Control features a 7075 t-6 billet aluminum lock down assembly button and catch band and includes a complete template and sticker for multiple settings. Retail is only $109.95.
     For added grip and stability, bolt on a set of Pro Circuit flow-through wide foot pegs. The wide foot platform offers riders better stability and is stronger than stock. The flow through design eliminates packing in muddy conditions. Opting for the titanium models offers weight savings over stock units. And the wider and deeper teeth on the pegs increase control and traction. Pro Circuit flow-through wide foot pegs are machined from titanium or 17-4 stainless steel that is processed with melonite for improved wear and corrosion resistance. Suggested retail for the stainless models is $109.95, the titanium models go for $229.95.
