I ordered as these are premium expensive product & Sportsbike shop was showing stock & were best price i found by a margin.Unfortunately they proved to be out if stock in uk & had to be ordered in with a lead time nearing 5 weeks. However they arrived earlier than the given expected date. Rizoma estimated fitting time is wildly optimistic but easy enough once i had interpreted wiring diagram. They look great, 100 times better than oe items & critically have completely eradicated the mirror 'buzz' & blurring. Despite what I read my own digital weighing of oe mirrors v rizoma including adapter plates there was a net weight saving of over 600 g
