BETA bikes 2016
The Beta RR and RS if you look under your cap there should be NO green section, then this EUR0001 filter is for you. If you have a green section under your fuel cap, you need our EUR0002 Mk4 filter, on our website.
This EUR0001 filter fits 250RR, 300RR ,350RR ,390RR ,430RR ,480RR ,430RS ,500RS
This filter also fits many after market fuel tanks that have the Small Acerbis fuel cap, like the older KTM dirt bikes, rear fuel cap adaptors on KTM690, front tanks on KTM990 1090 1190
So long as your tank has a 35.75mm to 41.5mm ID hole then this will fit.
If you have a 3D moto adaptor, we have a custom filter just for that: EUR0003
