Yamaha YZF 250 Extreme Big Bore Kit
Available for the 21-23 and 24-25 Yamaha YZF 250, Athena ' s new Extreme Big Bore Cylinder Kits with integrated GET Boost module expand the available applications of their Extreme Big Bore Kits lineup, now delivering the next-level performance they are known for to the ever-popular YZF 250. " This upgrade is engineered to let the latest YZF 250 generation reach its full potential with increased displacement, increased torque and increased power across the entire power curve, without compromises." The enlarged cylinder with forged piston increases displacement to a true 304 cc, turning the Yamaha into a fuller, more immediately responsive bike with continuous pull across the whole powerband.
" Thanks to the included, pre-configured GET Boost module, there ' s no need to redo mappings or modify the ECU. It is pure plug & play- install it, start the engine, twist the throttle and feel the difference immediately." Athena says that its race development programme gives it the experience and results to build Racing Technology that is built to last. By using premium materials such as a high-silicon aluminium cylinder, co-cast steel liner, forged piston and DLC-treated wrist pin the company says it can produce an upgrade kit that is designed to " perform at the limit ". " Even under extreme conditions, the high-seal MLS( Multi Layered Steel) head gasket ensures impeccable sealing thanks to laser-cut stainless steel, delivering total reliability, even when temperatures rise and the engine is under stress. This performance upgrade kit includes a high-grade aluminum cylinder with an oversized steel liner, a forged performance piston with pin and rings, and all necessary gaskets. Developed through Athena ' s extensive racing experience, " this kit ensures smooth, powerful, and progressive power delivery." The included electronic GET Boost module is precalibrated for this specific setup. GET Boost installs easily without ECU or wiring modifications with seamless pre-mapped integration. GET Boost connects directly to the injector and throttle body via a dedicated harness. The module is pre-mapped to deliver safe, reliable performance with
a power curve tailored to the new cylinder. The cylinder is made from high-silicon aluminum alloy with a steel liner fused using Athena ' s proprietary cocasting process, " ensuring optimal heat transfer and combustion sealing." The forged piston, CNCmachined and coated with molybdenum disulfide, " offers reduced friction and enhanced durability. The DLC-coated pin ensures maximum hardness and reliability." The included MLS head gasket is laser-cut from stainless steel to ensure perfect sealing and long-term durability, even under extreme conditions. Bore Diameter is 85.00 mm, bore gain is + 8 mm, compression ratio is 13.3:1 with 304.15 cc displacement.

Hyperlink- Tucano Urbano ' s first full face helmet
Owned by The Mandelli Group, urban and scooter apparel brand Tucano Urbano unveiled a prototype of its first ever modular / flip-up motorcycle helmet at EICMA in November 2024. After that world premiere Mandelli, has now confirmed that the Hyperlink modular has now finally arrived. Described as the first urban full-face helmet, it is P / J ECE 22.06 approved, with a removable chin guard and ultrawide visor. Designed specifically for those who ride daily in the city, where danger is always lurking, the twodimensional visor design allows for a 230 º horizontal and 105 º vertical field of view. Building on the success of their " super versatile, fresh, and colourful jet and demi-jet models ", HYPERLINK features an inimitable urban design- even in the ECE 06 approved versions. " Our first modular urban helmet is ' urban ' because we designed every detail to meet the needs of city riders," said Florian Martin, Marketing Director at MANDELLI. " So first, we aimed to provide the widest possible field of vision, to keep all potential hazards in sight. Second, we made the chin guard removable for practicality: our HYPERLINK can easily be stored under the seat or in the top case- even with another helmet. That ' s a real convenience for those riding in pairs or running around town with lots of

appointments and no desire to carry a helmet around." Three classic colours have been chosen but reinterpreted in a totally unconventional way. Matt Black, Matt Light Grey, and Glossy Nardo Grey are the three available colours for the standard version of HYPERLINK with Bluetooth-ready setup by MIDLAND. The integrated SMARTCOM by MIDLAND intercom version, ideal for riders who use travel time to catch up on phone calls, is available in Matt Black only. A Pinlock-ready version also available.
