The Wilbers shock optimizes both rebound and compression and offers a wider adjustment range than the stock unit, delivering clearly improved handling and increased safety.\u003c\/p\u003e\n\u003cp\u003eOur racing team’s development work flows directly into the shock’s individual setup — you receive a genuine race-replica configuration. The fork is supplied with linear springs ex-works; the Wilbers solution also uses linear springs but with rate options matched to rider weight, intended use, and (for track use) prevailing conditions. Depending on usage, we recommend SAE 5 or GP5 fork oil; with the Wilbers conversion, negative spring travel and response are optimized accordingly.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSwiveling, diagonally mounted compression reservoir.\u003c\/b\u003e\u003cbr\u003e\nFor tight installations, the reservoir mounts diagonally and swivels for optimal routing. A milled upper mount integrates the high- and low-speed compression adjusters; both compression and rebound feature 22 clicks. A pressure-control valve prevents hydraulic blocking and harsh impacts. Spring preload is continuously adjustable by hook spanner or optionally hydraulically. The reservoir angle can be re-indexed later by a trained Wilbers partner.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eProduct may vary from picture.\u003c\/b\u003e\u003c\/p\u003e","brand":"Wilbers","offers":[{"title":"Blackline \/ Hook Wrench \/ Std","offer_id":53609891037463,"sku":"643-1340-00","price":1425.0,"currency_code":"USD","in_stock":true},{"title":"Blackline \/ Hook Wrench \/ +10 mm","offer_id":53609891070231,"sku":"643-1340-01-+10","price":1425.0,"currency_code":"USD","in_stock":true},{"title":"Blackline \/ Mechanical (X-PA) (+$460) \/ Std","offer_id":53609891102999,"sku":"643-1340-00-XPA","price":1885.0,"currency_code":"USD","in_stock":true},{"title":"Blackline \/ Mechanical (X-PA) (+$460) \/ +10 mm","offer_id":53609891135767,"sku":"643-1340-01-XPA-+10","price":1885.0,"currency_code":"USD","in_stock":true},{"title":"Blueline \/ Hook Wrench \/ Std","offer_id":53609891168535,"sku":"643-1340-00-Blue","price":1425.0,"currency_code":"USD","in_stock":true},{"title":"Blueline \/ Hook Wrench \/ +10 mm","offer_id":53609891201303,"sku":"643-1340-01-Blue-+10","price":1425.0,"currency_code":"USD","in_stock":true},{"title":"Blueline \/ Mechanical (X-PA) (+$460) \/ Std","offer_id":53609891234071,"sku":"643-1340-00-Blue-XPA","price":1885.0,"currency_code":"USD","in_stock":true},{"title":"Blueline \/ Mechanical (X-PA) (+$460) \/ +10 mm","offer_id":53609891266839,"sku":"643-1340-01-Blue-XPA-+10","price":1885.0,"currency_code":"USD","in_stock":true},{"title":"Nightline (+$90) \/ Hook Wrench \/ Std","offer_id":53609891299607,"sku":"643-1340-00-Nigh","price":1515.0,"currency_code":"USD","in_stock":true},{"title":"Nightline (+$90) \/ Hook Wrench \/ +10 mm","offer_id":53609891332375,"sku":"643-1340-01-Nigh-+10","price":1515.0,"currency_code":"USD","in_stock":true},{"title":"Nightline (+$90) \/ Mechanical (X-PA) (+$460) \/ Std","offer_id":53609891365143,"sku":"643-1340-00-Nigh-XPA","price":1975.0,"currency_code":"USD","in_stock":true},{"title":"Nightline (+$90) \/ Mechanical (X-PA) (+$460) \/ +10 mm","offer_id":53609891397911,"sku":"643-1340-01-Nigh-XPA-+10","price":1975.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/7113\/0135\/files\/643compqs_9e5b582b-ef81-4665-b27a-315b762c0f49.jpg?v=1782979217","url":"https:\/\/epmperformance.com\/products\/wilbers-shock-absorber-type-643-competition-qs-aprilia-tuono-v4-1100-factory-kg-643-1340-00","provider":"EPM Performance Imports","version":"1.0","type":"link"}
