KTM/HUSKY/GASGAS 300 2-STROKE HOP-UP GUIDE
This category has blossomed with the popularity of the 300cc two-stroke dirt bike. It started as a niche market that was pretty much owned by KTM. It has taken a good chunk of the off-road market and has been the benefactor of technological gains in performance via fuel injection, state of-the-art suspension, light weight, and dedicated machines that make tuneable and useable power.
Through the parent company, which owns Husqvarna and GasGas, the 300’s tentacles have been stretched, massaged and refined. We now have off-road bikes that have rewritten what a true off-road machine must perform like. So, the first “300 Performance Guide” is dedicated to the Austrian machines. The number of companies supporting this group is substantial, so this will be broken down into parts dealing with power, chassis, suspension and protection. Not every product from these manufacturers is shown, as we’re handcuffed with space issues; however, we’ll showcase more products in the online version. This month we’re starting with Power, Protection and Chassis. Next month we’ll delve into Suspension, Power, and Chassis performance products. Down the road we will have a similar guide for the Sherco, Beta and Rieju machines.

COPPERSMITH AERO HYBRID KIT FOR WP AER 48 AIR FORKS
Price: $TBA
The Coppersmith kit allows racers to use their existing WP fork legs, and only the damping leg of the WP fork is modified by upgrading the damping with an Ohlins TTX22 cartridge kit and a coil spring. This lets the fork do a better job of handling the small- to medium-sized bumps, and as the fork compresses, the stock air leg kicks in to stiffen the fork. The TTX technology uses a positive pressure-balance system via twin-tube technology. The gas-pressurized dividing piston inside the cartridge pushes the hydraulic fluid back into the low-pressure side, and the result is improved performance and zero cavitation.
PRO CIRCUIT LINKAGE
Price: $445.00
Pro Circuit’s linkage system for your new-model KTM, Husqvarna, and GasGas brings the bike’s handling performance to an entirely new level. The 2023–2024 models come equipped with a linkage system that results in lazy and soft feeling. Both OEM designs made it difficult to reach optimal handling performance and forced the use of shock springs on both extremes of the spectrum to compensate.
The new Pro Circuit linkage system features mechanical advantages that allow for the use of a more true-to-weight spring rate and to reach the ultimate sweet spot in handling for your new-model KTM, Husqvarna, and GasGas.
