@samuel_zxmoto: zx820rr stand with bmw s1k The Zhang Xue 820RR (ZX820RR) is a modern middle-weight supersport motorcycle built with fully independent powertrain technology and race-tuned chassis geometry, focusing entirely on competitive engine performance and lightweight body specifications for both street legal use and track riding. Powered by a self-developed 819cc inline-three liquid-cooled four-stroke DOHC 12-valve engine with a 120° evenly spaced firing crankshaft and dual counter-balance shafts, the unit delivers smooth high-rev stability and strong linear torque output. This powerplant features titanium valves, forged connecting rods and lightweight magnesium alloy pistons, ensuring high durability under continuous high-rpm operation while keeping the engine dry weight at only 52kg. Three official tuning versions provide distinct performance levels. The standard road variant produces 135 HP at 12000 rpm and 80 N·m at 9500 rpm, achieving 0–100 km/h acceleration in 2.81 seconds with a top speed of 280 km/h. The RR-R upgraded version outputs 145 HP and 85 N·m with a 299 km/h electronic speed limiter. The top RS race version reaches 153.6 HP at 15250 rpm and 85 N·m torque, sprinting 0–100 km/h in 2.6 seconds with a 16000 rpm redline. A 6-speed quick-shift transmission and variable-valve exhaust system further refine throttle response and racing sound characteristics. In body and chassis specifications, the 820RR adopts an aviation-grade aluminum twin-spar frame and forged magnesium swingarm for outstanding rigidity and precise handling. Its main dimensions measure 2085mm × 725mm × 1135mm, with a 1410mm wheelbase, 810mm seat height and 135mm ground clearance. The standard curb weight is 193kg, while the track-focused RS version drops to 168kg, delivering a class-leading power-to-weight ratio up to 0.91 HP/kg. The 16.5L fuel tank balances daily usability and track endurance. For suspension, standard models feature fully adjustable 41mm KYB inverted front forks and rear multi-link shocks, while high-end trims equip Öhlins DLC-coated racing suspension for superior compression and rebound control. The braking system consists of a 320mm front floating dual disc with radial four-piston calipers and a 260mm rear single disc, supported by cornering ABS for safe aggressive riding. It mounts standard 120/70 ZR17 front tires and 180/55 ZR17 rear tires. Aerodynamic winglets increase high-speed downforce by 30%, stabilizing the chassis during hard acceleration. A six-axis IMU governs 10-level traction control, launch control and multiple riding modes, perfectly matching the engine’s aggressive power delivery and making the Zhang Xue 820RR a fully competitive global middle-weight supersport model. #zxmoto #zx820rr #wsbk #racing #exhaust #exhaustsound #zx500rr #fyp #motorcycle #foryoupage #rider #bike #bikelife #biker #zxjc #riding #modified #modification #Evanbros
