Between approximately \u003cstrong\u003e3000 and 5000 rpm\u003c\/strong\u003e, and at partial accelerations, the engine shows a fuller response and a clear feeling of \u003cstrong\u003emore available torque\u003c\/strong\u003e, facilitating control in technical riding.\u003c\/p\u003e\n\u003cp\u003eThis behaviour makes the product particularly suitable for \u003cstrong\u003etrail and hard enduro\u003c\/strong\u003e, where traction, predictability, and smooth power delivery are crucial for performance and for reducing rider fatigue.\u003c\/p\u003e\n\u003ch3\u003eHow it Works\u003c\/h3\u003e\n\u003cp\u003eIn 2-stroke engines, pressure waves generated in the exhaust system help increase power at high RPMs but can hinder efficient cylinder filling at lower RPMs. This effect ultimately penalizes the engine's torque and response in the RPM ranges most used in technical riding.\u003c\/p\u003e\n\u003cp\u003eThe larger volume exhaust valve cover introduces an additional chamber that acts precisely in these conditions. When the valve is still closed or in the initial opening phase, part of the pressure waves are smoothed within this chamber, reducing their negative interference with the gas flow.\u003c\/p\u003e\n\u003cp\u003eThe result is a more effective cylinder filling at \u003cstrong\u003elow and medium RPMs\u003c\/strong\u003e, translating into a more immediate throttle response, greater control, and more usable power delivery from early on.\u003c\/p\u003e\n\u003cp\u003eAfter a development process based on practical tests and careful tuning of the internal volume, a solution was achieved that provides \u003cstrong\u003econsistent and measurable gains in the low and medium RPM range\u003c\/strong\u003e, significantly improving engine behaviour where it really matters.\u003c\/p\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eCompatible with \u003cstrong\u003e250 cc and 300 cc TBI\u003c\/strong\u003e motorcycles from the following brands:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eKTM\u003c\/li\u003e\n\u003cli\u003eHusqvarna\u003c\/li\u003e\n\u003cli\u003eGasGas\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFor 2024 and 2025 models only\u003c\/strong\u003e\u003c\/p\u003e\u003cdiv class=\"tags_desc\"\u003e\u003cdiv field=\"Compatibilidade\"\u003e\n\u003cstrong\u003eCompatibility\u003c\/strong\u003e enduro_husqvarna_te_250tbi_2024, enduro_husqvarna_te_300tbi_2024, enduro_ktm_exc_125tbi_2024, enduro_ktm_exc_250tbi_2024, enduro_ktm_exc_300tbi_2024, enduro_gasgas_ec_250_2024, enduro_gasgas_ec_300_2024, enduro_gasgas_ec_250_2025, enduro_gasgas_ec_300_2025, enduro_husqvarna_te_300tbi_2025, enduro_husqvarna_te_250tbi_2025, motocross_ktm_sx_250_2025, enduro_ktm_exc_250tbi_2025, enduro_husqvarna_tc_250_2025, motocross_gasgas_mc_250_2025, motocross_ktm_sx_300_2025, enduro_ktm_exc_300tbi_2025, enduro_gasgas_ec_250_2025, enduro_gasgas_ec_300_2025, enduro_husqvarna_te_300tbi_2025, enduro_husqvarna_te_250tbi_2025, motocross_ktm_sx_250_2025, enduro_ktm_exc_250tbi_2025, enduro_husqvarna_tc_250_2025, motocross_gasgas_mc_250_2025, motocross_ktm_sx_300_2025, enduro_ktm_exc_300tbi_2025\u003c\/div\u003e\u003c\/div\u003e","brand":"DOCA","offers":[{"title":"Default Title","offer_id":52371504333128,"sku":"011DCPV001-BL","price":67.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0649\/0449\/5321\/files\/12523647896857436254.jpg?v=1769341703","url":"https:\/\/megamotopecas.com\/en\/products\/tampa-expansao-de-valvula-de-escape-ktm-tbi-24-25","provider":"Mega Moto Peças - Armazém de Peças e Acessórios","version":"1.0","type":"link"}
