You can buy a 1000cc oe 1200cc Vincent engine or complete bike made from new part from Maugham and Sons:

"It is possible to build a brand new Vincent twin engine. In fact, a completely new bike can be made. One such machine sold at auction a few years ago and fetched £30,000. Brand new engine cases start at £1950. We used to supply engine cases to Matt Holder and machine them right here. But these days we’ve got so much work on that we use John Wyatt cases that come ready machined for Steve to rebuild an engine."

They are replicas that are claimed to be better than the originals, due to improved manufacturing and materials...they (currently 2010-2011) sell for around £150,000, which is not cheap but the originals are now fetching upto £286,000 at auction. I was present in October 2010, at the Haynes Museum Classic bike auction when this record sale was made;

In South Australia, Greg Summerton makes complete J.A.P. engines, and races them. Greg says, "Internally, these engines are currently only loosely based on the JAP engine layout, but dimensionally they are all my own design. Nothing from my engines will suit or fit a genuine JAP." Website:

Since Vincent employed an Australian design Engineer, (Phil Irving), an Australian Engineering company, KH Equipment, in Melbourne, (run by the Horner brothers), decided to continue development of the 1000cc V-twin Irving designed. They set up a subsidiary company called HRD engineering - Horner Race Development - recalling the HRD company that became Vincent Motorcycles. They have massively increased the power output to 165 brake horse power, and have won the Daytona Battle of the Twins in 2008, and other races. The bike is available in 6 versions, with two dispacements - 1300cc and 1600cc. See website:




JMC Classics, based in Hertfordshire, England, make replicas of the Egli Vincent. The Egli Vincent was a chassis designed by Swiss motorcycle engineer, Fritz Egli in the late 1960. They also make a Norvin replica - a Vincent engine in a Norton featherbed frame. The bikes come in 2 colours - black or red, with various specifications to the buyer's taste, such as single or dual seat, 1000cc or 1200cc, electronic or magneto ignition, black or polished engine; also a race clutch and electric start are standard. See the website:

The original company (10 miles from JMC Classics), was called "John Mossey Restorations" (JMR). This became HMR for a year but then was closed down. The story was "JMR assets and management was taken over by investors which removed John Mossey. The investors developed the relationship with the Hailwood family and rebranded the business and bike "HMR" for about one year before business was closed down. In parallel John Mossey established JMC and resumed the production of the motorcycles that were manufactured in the previous (company) structure."

Here is the old HMR catalogue:

The Hesketh 1000cc v-twin was developed in 1974, with 4 valves per cylinder and overhead went into production before development was complete, but development has continued by Broom development Engineering, who have changed tyres, brakes, added oil cooling improvements, and gearbox modifications. They make about 12 per year at their Northamptonshire facility. On the left above is the original and on the right the current v1000 model. Note back to spoked wheels and re-positioning of calipers.

Norcroft-Enfield. The Norcroft venture was started by Bill Hurr and Richard Hurst. Hurr noticed that a Royal Enfield Bullet has the same bore and stroke as a Vincent Balack Shadow and Rapide. After successfully designing a 50-degree v-twin with Enfield top ends, they got Metisse to design a custom built rolling chassis. Financial problems led to a postponing of production plans. The bike is still under development. UPDATE 2014: Now going into production - see links below

EnfieldV-twin CarberryEnfield

The Carberry Enfield is made by Paul Carberry and Ian Drysdale in Australia. They took the top ends of two 500cc Royal Enfield single cylinder engines, which are still being manufactured in India, and they designed a crankcase to turn them into a 55-degree 1100cc V-twin. UPDATE Feb 2014: Carberry have stopped production

Enfield Musket. Aniket Vardhan moved from Delhi to USA since he loved the sound of the Harley Davidson v-twin, and wanted to build a v-twin out of 2 Royal Enfield Bullets. He built a 700cc v-twin from two 350cc bullets and is currently working on the 1000cc version, to be available as economical kits, to convert a bullet into a v-twin. The bike sounds fantastic - The angle of the vee is 70 degrees. Website:

Clutch springs were beefed up after this road test revealed some clutch slip due to increased power:


Amazing tick-over:


UPDATE: Jan 3 2012: Wooden casting patterns for the 500 v-twin now complete... v-angle changed to a more compact 59 degrees, than the 70 degree angle of the 700cc v-twin...hope the tick-over still sounds as sweet


UPDATE!!! Musket 998 now finished! See news page: V-Twin Innovator News
