  •  Very rare genuine Bonneville T120 ‘Competition’
  •  U.S. export returning to the U.K. in 2003
  •  Stunning restored condition
  •  Matching numbers bike
  •  Extremely low mileage


Commemorating Johnny Allen’s Triumph land-speed record runs at Bonneville Salt Flats in 1956, the Triumph Bonneville was launched at the 1959 Earls Court Motorcycle Show and was quickly dubbed ‘The best motorcycle in the world’.

Numerous competition entries followed with the first being in 1959 at the Thruxton 500. The T120R was soon developed by Triumph engineers utilising precision-machined cylinder heads and crankcases to further their track successes during the 1960’s.

Outperforming many of it’s American rivals, the T120C was also offered as a lightweight sports street-scrambler, and naturally pandered to the lucrative American market.

Having had a complete cosmetic and mechanical restoration since it’s import in 2003, this highly desirable T120C is in fantastic condition and benefits from a recent service and tune by a professional mechanic - and not forgetting an expert detailed polish by the owner.

Completely ready to admire and ride, this rare ‘Bonnie' is not to be missed… 



  •  Manufactured on the 16th September 1960
  •  Despatched to the USA on the 21st September 1960 
  •  First registered in the U.K. on the 1st June 2003
  •  Up to date V5 plus two previous V5’s
  •  Triumph Manufacturer’s ‘Statement of Origin’ 
  •  The Triumph Owners Motor Cycle Club dating / confirmation letter

  •  Last ‘Pass’ MOT in 2011 at 1,456 miles (exempt)

Looking at the accompanying Statement of Origin and a letter from The Triumph Owners Motor Cycle Club, this bike was despatched to The Triumph Corporation, Baltimore, in September 1960 and was subsequently supplied to a distributor in Indiana in June 1961.

Initially residing with the first U.K. owner’s in Hertfordshire, Surrey and Dorset, the current owner, and long-term Triumph enthusiast, acquired it from a collector in January of this year.  

Although the mileage cannot be verified, the 2010 MOT indicates a mileage of 1,336, which does suggest a mechanical rebuild was undertaken soon after repatriation to the U.K.

About Max Bids

The max bid process allows you to bid without any hassle.
Enter your maximum bid and we will then bid on your behalf to ensure you're the highest bidder - just enough to keep you in the lead and only up until your maximum.


C&C prevent auction snipers from bidding in the last seconds to win an auction.
Auctions are extended by 3-minutes if anyone bids within the last 2 minutes to allow other bidders to react and counter-bid.

Auto-bidding increments

  • If your maximum bid is equal to or below the reserve price, your maximum bid will be applied in full if you are the highest bidder.
  • If you are the highest bidder and place a maximum bid above the reserve, we will automatically put in the reserve as your first bid.
    • Once the reserve has been met, Car & Classic will make sure you are the highest bidder using only the bidding increments stated below.
    • We will keep you in the lead up until your maximum bid OR the increment closest to your maximum bid, providing your maximum bid is enough to cover the increment value.

Bid Amount Increment
£0 to £10,000 £100.00
£10,000 to £50,000 £250.00
£50,000 to £100,000 £500.00
£100,000+ £1000.00

Automatically outbid immediately

When you place a max bid and are outbid immediately that means that another bidder has placed a max bid limit which is higher than yours.
You can bid again and we will use our automatic bid system to try and get you as the highest bidder.

Matching max bids

When there are two max bids of the same value, the one placed first remains the lead bidder.

What are pre-bids?

A pre-bid means you’re able to place a bid before the official start of the auction.
You will be notified whether or not you are the highest bidder when the auction starts.

Problem with your bid

Bids are contractually binding. To help protect you, we have some rules in place if we think it's been mistyped. Please check and amend what you have entered.
