So I knew that Pyramid do a front fender extenderat taround the £21 mark but I’m a cheapskate. Ebay revealed one for around £16 but with a fiver postage, so £21.
I then noticed the ‘Make an Offer’ button, which I did. As I did this I noted that the seller was Pyramid, go figure.
Anyhow, my offer of £11 was accepted and there are a couple left if you fancy one 
Would have been nice, but I paid the full price a couple of months ago!
Ah well, but have you sourced a taller screen 
My next requirement
I have the Givi screen. Have a look in the “Stelvio replacement screen” thread.
