Increase Performance for new KTM and Husqvarna 250 Two-Stroke Models

2020 KTM 250 SX Exhaust

 

Recently released from Pro Circuit is their two-stroke lineup of pipes and silencers for the 2020 KTM 250 SX and Husqvarna TC 250 models. Ready to bolt on and head to the track or trail, Pro Circuit's Works Pipe, R-304 silencer and others in the exhaust line offer a noticeable performance and horsepower boost across the entire RPM range. KTM and Husqvarna riders will be excited to add a little bit more fun into their riding experience the next time they shred a track or desert trail.

 

Works Pipe The original Pro Circuit Works Pipe offers unparalleled performance and power for every two-stroke application. Increased horsepower and torque gains will quickly be noticed across the entire RPM range. The unplated, oiled metal finish requires some maintenance, but really gives your bike that "works look".

 

Platinum Pipe The Platinum Pipe offers the same performance gains as the Works Pipe, but is a more ideal choice for extreme weather condition riding. It is constructed of AKDQ high-quality carbon steel and includes a nickel plated finish to reduce rider maintenance and to help protect the pipe against nature's elements.

The titanium and carbon Kevlar construction offers the "factory" look and appearance while reducing weight. The Ti-2 is for closed-course racing only.

 

R-304 Silencer The R-304 Shorty Silencer was developed as a full-race two-stroke silencer. The compact design of the short aluminum canister offers optimum performance gains and is recommended for closed-course racing only. Hex head screws are used to secure the inlet cap and can be removed easily for quick re-packing of the silencer.

 

304 Silencer The 304 Factory Sound Silencer is recommended for most two-stroke applications. The slightly longer body offers added top-end performance while reducing noise output. The brushed aluminum body and stainless steel inlet tube and end-cap gives you a silencer that looks as good as it performs.

 

Type 296 Spark Arrestor Silencer The Type 296 Spark Arrestor Silencer is a quiet spark arrestor that should be used when riding in noise sensitive areas or any National Forest. The Type 296 silencer is also U.S. Forest Service approved and will reduce your bikes noise level at or near 96dB on most models.

2019 YZ65/YZ85 VForce4R Reed Valve

Enhance Performance for the 2019 Mini Yamaha Models

VForce4R YZ65 and YZ85

 

Recently, Pro Circuit stocked the new VForce4R reed valve system by Moto Tassinari for the 2019 YZ65/85. Moto Tassinari's VForce4R reed valve system is designed with a shallower petal angle which allows them to open further and with much less force than that of the stock reed system equating to better fuel flow and ultimately more power. The shallower reed petal angle also reduces the tension on the petals resulting in increased strength and durability keeping your minibike rider out on the track longer. Moto Tassinari's VForce4R reed valve system also incorporates an all-new manifold, reed cage and air guide to boost overall performance.

 

Over the years Moto Tassinari has made many upgrades to their VForce reed systems and the VForce4R reed block for the 2019 YZ65/85 is no exception. Pick up a VForce4R reed system at Pro Circuit for your minibike rider and ensure he or she is getting the best performance from their 2019 YZ65 or YZ85.

Pro Circuit 2019 YZ85 Exhaust

Two-Stroke Pipes and Silencers For The New Yamaha Mini Model

YZ85 Exhaust

 

For years we have been crafting championship-winning two-stroke pipes and silencers for some of the fastest mini racers on the planet. We expect the same results with our Works and Platinum pipes, Ti-2, 304 and Type 296 silencers for the new 2019 Yamaha YZ85. Our pipes and silencers offer noticeable performance and horsepower gains across the entire RPM range. Your little one will be pumped with the performance of his or her new YZ85 model, so bolt on a Pro Circuit pipe and silencer and continue up through the mini ranks the right way.

 

2019 YZ85 Works Pipe The original Pro Circuit Works Pipe offers unparalleled performance and power for every two-stroke application. Increased horsepower and torque gains will quickly be noticed across the entire RPM range. The unplated, oiled metal finish requires some maintenance, but really gives your bike that "works look".

 

2019 YZ85 Platinum Pipe The Platinum Pipe offers the same performance gains as the Works Pipe, but is a more ideal choice for extreme weather condition riding. It is constructed of AKDQ high-quality carbon steel and includes a nickel plated finish to reduce rider maintenance and to help protect the pipe against nature's elements. The Platinum Pipe also features hand welded and pounded seams and reinforced mounting brackets and stingers for increased durability.

 

2019 YZ85 Ti-2 Shorty Carbon Kevlar/Titanium Silencer The Ti-2 Shorty Carbon Kevlar/Titanium Silencer is the latest piece of racing technology offered by Pro Circuit and is guaranteed to be a favorite for most two-stroke riders. The Ti-2 is similar to the popular R-304 silencer except it is constructed with a carbon Kevlar shell, titanium tubing and titanium end-cap. The titanium and carbon Kevlar construction offers the "factory" look and appearance while reducing weight. The Ti-2 is for closed-course racing only.

 

2019 YZ85 304 Factory Sound Silencer The 304 Factory Sound Silencer is recommended for most two-stroke applications. The slightly longer body offers added top-end performance while reducing noise output. The brushed aluminum body and stainless steel inlet tube and end-cap gives you a silencer that looks as good as it performs.

 

2019 YZ85 Type 296 Spark Arrestor Silencer The Type 296 Spark Arrestor Silencer is a quiet spark arrestor that should be used when riding in noise sensitive areas or any National Forest. The Type 296 silencer is also U.S. Forest Service approved and will reduce your bikes noise level at or near 96dB on most models.

Jim "Bones" Bacon Retires

Pro Circuit's Expert Suspension Tuner Puts Down The Screwdriver

Bones Retires

 

Pro Circuit Products, Inc. is announcing today that Jim "Bones" Bacon, long-time suspension technician, will retire from his role as head suspension tech, yet still plans to assist the suspension department in the future.

 

Letter From Bones:

 

"Pro Circuit has been my life for the last 34 years. When Mitch Payton gave me a chance to fulfill a lifelong dream of working in the motorcycle industry back in 1984 I felt like the luckiest kid in the world. In the beginning, I was taught and given advice from a few key people which got me kick-started in the right direction. With this under my belt and working for the powerhouse Pro Circuit Racing Team, it gave me the opportunity to do suspension for a lot of top-level riders in both motocross, supercross, as well as off-road over the years."

 

"With this being said, I have officially retired from the day-to-day operations at Pro Circuit. I will still be around in an advisory role when needed, which will include helping with special projects, helping with the testing of customer suspension as well as the amateur riders. Mitch and I have chosen Adam Walters to take my place in running the suspension department at Pro Circuit. I have known Adam for a long time and could not think of a better person to take over for me. Adam comes in with a lot of experience working with Showa USA, other race teams, as well as racing himself for a number of years. He has also worked with riders in both motocross, supercross, as well as off-road before. With Adam, we will be able to grow the supsension department to a whole new level. Our goal is to offer our customers a top-level experience like no other before when getting their suspension done."

 

"In closing, I have assembled a list of all the professional riders that I have had the pleasure to work with over the years. I would like to thank all of you for trusting in me to do a good job for you, as well as the young up-and-coming amateur riders that I have worked with that never, or have not yet made it to the professional level. It has been a fun ride, but I am going fishing now."

2017 Husqvarna TC 85 17/14 Dirt Rider Project Bike

How to Make a Fast Mini Faster

A young racer could find themselves on the gate against one or more of the nation's most promising factory recruits on their finely tuned factory machines. Luckily for these mini privateers, they have access to the same equipment that we put on this project 2017 TC 85 for young racer Jack Carrigg.

 

Jack rode the 2017 TC 85 in stock form first to get a good feel of what we had and where we wanted to go with it. The feel of the cockpit was well liked immediately. The bike felt narrow between the legs, its seat seemed long and fairly flat, and the controls were well positioned and with that great hydraulic clutch that's easy to pull. The TC 85 is a bit longer and taller feeling than most of the Japanese brands, and it did take a few laps to begin trusting the lean in through inside ruts at speed...
