Show original supplier description
The Race Tech Gold Valve Kit is an advanced modification for the Honda Grom MSX125, designed to significantly improve fork performance. Stock Grom forks are noted as underdamped and undersprung, lacking sufficient travel. This Gold Valve Shaft Kit addresses these shortcomings by providing increased travel and improved damping characteristics. Upon installation, one fork leg will handle compression damping, while the other will manage rebound damping, a departure from the identical stock configuration. This installation is considered advanced and necessitates specialized tools, including a Shaft Holding Tool (TFSH 31) and a 14mm Allen wrench (TMWA 14). The process involves careful disassembly of the stock forks, heating the fork bottom to loosen locking compound (note the left-hand threads), and precise assembly. Key specifications for installation include a fork bottom torque of 50 ft-lbs (68 NM), a plug torque of 30 ft-lbs (41 NM), and a preload range of 5-10mm. The modified forks will also be 20mm longer than stock, offering geometry benefits and enhanced bottoming resistance. Proper fork fluid measurement and installation of Race Tech stickers are also part of the process.
