JAP Motors Produces New V-Twin

J. A. Prestwich Motors.
JAP once built motors that powered some of the most iconic machines in British motorcycle history, including Brough Superior amongst the 137 brands they supplied to, which included initially their own machine. They produced both singles and mighty V-Twins and now a 1298cc V-Twin has been re-manufactured and used to power an all-new British bike that has yet to be named. The new project is the brainchild of Alex Cord who once owned Brough Superior and has spent £300,000 to bring his childhood dream to fruition.

The 50 degree V-twin motor has been improved in places and uses modern materials and techniques as you would expect, like electronic ignition. Currently it uses a carburetor, but plans are already underway for an injection unit to meet current regulations. The motor is mounted in a copper plated frame similar to the famous ‘Copperknob’ and the appearance is similarly very minimalistic! Cost is just under £30,000 for the hand-built machine.

If you want to build your own J.A.P v-Twin engine for much less money why not check out these guys http://www.mfcpatterns-castings.co.uk.
They have been producing parts for J.A.P engines since the 1980s, parts that are used by a large number of J.A.P v-twin engined bikes and cars. They also produce tooling & castings that are used by many of the top UK classic motorcycle people.

Just what we all need! another over priced motorcycle with no dealer network for spares & service, its just someone claiming to be J.A.P.
You dont just buy the rights to a name many years after the factory closed down and then claim some kind of connection.
TR -JAP is an acronym... August 3, 2009 02:09 PM
... and it stands for "J. A. Prestwich." They were and are British motors. The originals are very valuable. Harley sheep idiot, indeed.

Not to mention that J.A.P. doesn't stand for Japanese in this case...

Milwaukee Mike...you truly are a Harley sheep idiot. I have a Harley (a 2007 Buell XB12Scg) that I bought new in 2006 and it's the biggest piece of sht I've ever owned. It has given me more problems in the two years that I've owned it than my 1991 Suzuki ATV, 2005 Honda CRF50, and my 1995 Chevy S-10 have given me. Let's see the voltage regulator died at around 1,000 miles, the cylinder base gaskets started leaking at around 5,000 miles and the brand new engine had to be torn down, and the bike still leaks and consumes oil. And just the other day, at around 10,000 miles, the clutch cable support, basically a cheap Chinese metal spring, snapped for no reason. Yep, Harley is quality! I doubt I'd ever buy another one. I am NOT alone in my experiences with Buells or Harleys. And Harleys are NOT even close to being 100% American. Let's see my Buell has Showa suspension, wheels that have "CHINA" cast into them, etc...
