Check out Custom works Zon, Japanese builders. They have taken what might be considered one of the least suitable doner bike to be converted to a cafe racer the Bmw K1600

Now I know how good these bikes are I am on my second used only for European tours, last used September 18.
Remember the Lotus offering which I liked, this Japanese offering is on similar lines though bigger and heavier due to being built on this road bike and credit where it is due.

What I think is great now that there are many in-house small designers bringing a fresh look to main stream machines and even improving on some of the best.
