Bridgestone – Bridgestone Battlax Adventure A41 & AT41 - Front, including A41F radial fitments, A41F G-spec sizes, Adventure Trail AT41F front tires and 19 and 21 inch adventure front sizes, gathers the leading edge of the Battlax adventure family in one place. Front tires do the talking on a big adventure bike: they carry the steering feel, the initial bite into a corner and most of the braking load. The A41F leans toward tarmac, with a silica-rich street compound and a tread pattern that clears water quickly, while the AT41F shifts the balance toward gravel, fire roads and hardpack without giving up highway composure. Sizes here span 90/90-21, 100/90-19, 110/80R18 and R19, 120/70R19 and 120/70ZR17, so tall-wheel travel bikes and road-biased adventure tourers are both covered. Riders notice the difference immediately in wet weather stability and in how neutrally the bike falls into a turn with a fully loaded set of panniers behind them. Take a moment to check the sidewall marking against your bike's original front specification before ordering so the profile and speed rating stay correct for the chassis.
