{"product_id":"derbi-diffuser-quick-restricter","title":"Quick restricter for Derbis: header to expansion chamber","description":"\u003cp\u003eQuick restricter (restrictor plate) to be installed between the header pipe and the expansion chamber.\u003c\/p\u003e\n\u003cp\u003eFits almost all mopeds with Rabasa technology, such as Derbis, Aprilias, etc.\u003c\/p\u003e\n\u003cp\u003eBefore ordering, please check that the bolt spacing in the three-bolt connection of the exhaust expansion chamber is 51-52 mm measured from center to center. Also fits other mopeds with a three-bolt exhaust connection and matching bolt spacing.\u003c\/p\u003e\n\u003cp\u003eThe restrictor is delivered with a center hole slightly smaller than stock. Hole size is 7 mm. With this, all models will surely run under 45 km\/h.\u003c\/p\u003e\n\u003cp\u003eThe restrictor is easy to drill yourself if it restricts power too much. The best tool for drilling is a step drill bit with the desired diameters. It is recommended to increase the hole size a couple of millimeters at a time until the desired restriction is achieved, to ensure the restrictor does not accidentally become too large: drilling the hole is easy – making it smaller is difficult.\u003c\/p\u003e\n\u003cp\u003eIf you know your desired size in advance, you can contact customer service when placing your order, and we will drill the hole before delivery.\u003c\/p\u003e","brand":"BikeRiseOutlet","offers":[{"title":"Default Title","offer_id":52761735528795,"sku":"VT-KU-PPT-DERPAI-1","price":9.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0990\/4000\/2395\/files\/VT-KU-PPT-DERPAI-1.jpg?v=1775906228","url":"https:\/\/www.bikeriseoutlet.com\/en\/products\/derbi-diffuser-quick-restricter","provider":"BikeRiseOutlet","version":"1.0","type":"link"}
