Shibata GRK Lightweight Front Knuckle Ver.TAKU (R31S348PU), known as the "T Knuckle". Developed at the request of GRK RACING driver TAKU for strong front-end tracing and speed, it won both solo and tandem at 2026 Tohoku Style Rd.4. Also fits the GS2MOD with straightforward setup.
Notes: Coming from Ver.Y or V1 knuckles with Shibata axles (R31S024 / R31S064 / R31S131), a 1mm idler spacer (R31S123) may be needed for clearance. Coming from the stock resin knuckle, 1050 x 4mm bearings are required (sold separately).
