Welcome to the forum, eBay is probably your best place for choice as most shops only usually have one brand
I went for R&G from ebay or can be bought or ordered from most bike shops, very easy to fit, it could save you lots of money protecting your rad from stone chips.
R&G. this was the first item I fitted to my RR8 Still surprised the this is not a standard fit on motorbikes in the land of dirty farmers and gritters
