2011 Pitster Pro FXR125R Review

After the recent media blitz, you may have thought that Yamaha was the only manufacturer on the market offering a “real” 125cc sport ATV. If so, you could be mistaken. Pitster Pro, an American based company with manufacturing in China, carries a bit of street cred for building a line of pretty decent race oriented pit bikes. They came up with their pit bike designs by looking at what was working in the pit bike-racing world, then applying it to their stock machines. The end result was a reasonably competitive machine at a fraction of the price of purchasing and building up a Japanese pit bike.

Back in 2008, Pitster Pro decided to apply their business model to building an ATV. They used a Honda TRX90s built up for national racing as a base line for their design. The result is the Pitster Pro FXR 90, 125, and 150, which according to several magazine tests, are pretty impressive performers. Unfortunately, we have heard this before with the original Xtreme Typhoon 125 which proved to be a poor design and extremely unreliable.

To see if it lived up to the hype, we decided to test Pitster Pro’s FXR125. This displacement has the largest number of available classes for youth racers and sets up a nice shootout between itself and the Raptor 125.

Technically Speaking

The Pitster Pro is powered by a horizontal design 124cc air-cooled, two-valve, single overhead cam four-stroke engine. The engine features a 10.2 to 1 compression ratio and is nearly square with a bore of 54.5 and a stroke of 53mm. Harnessing the power is a close ratio four-speed transmission with a manual clutch. Air and fuel are fed to the engine by a 22mm carburetor. Most race oriented youth ATVs use a carburetor-mounted clamp on filters. The FXR’s filter is mounted on a trick looking aluminum air box.

A kick-starter turns the engine over with no electric start option. The kick-start lever has a long downward stroke, which we are told, forces Pitster to equip it with a hinged heel guard that must be flipped up to start the engine. This is a pain and probably why our dealer removed the heel guards prior to our picking up the ATV. Pitster needs an electric starter, or to address the design of the kick-starter, to allow for a more conventional heel guard .

The Pitster Pro’s chassis is constructed of chromoly and looks pretty stout. The dual a-arm front-end features camber and caster adjustments, something only found on a handful of stock 450cc models and most high-end aftermarket a-arms. The rear of the machine features a lightweight machined aluminum swing arm with a round housing style axle carrier making chain adjustments a breeze. The chassis even features an anti-vibe steering stem.

Piggyback reservoir equipped GPX shocks reside at both ends. The shocks feature preload, compression, and rebound adjustments and control 8 inches of wheel travel up front and 9 in the rear, offering class leading suspension travel and adjustability.

Hydraulic disc brakes front and rear slow the FXR125. The front brakes feature dual piston calipers and the rear end features a wave style rotor providing better cooling and better brake pad clean out. The rear brake is operated with a uniquely designed reverse facing foot pedal. The front brakes are operated using the right side, handlebar-mounted hand lever. 

Like Pitster Pro’s pit bikes, the FXR comes with many race ready features. Lightweight aluminum rims are wrapped in Carlisle holeshot-style tires, 18×6-10 front and 18×6.5-8 rear. This wheel and tire setup has been very popular in motocross racing for years.  A cross-country style aluminum front bumper, chassis skid plate, plus sprocket and rotor guards protect the chassis from trail obstacles. For additional safety and to make the machine race legal, the FXR even comes with nerf bars and a tether kill switch.
