1968 Triumph Bonneville T120


  • Restoration completed in 2018
  • Full engine rebuild
  • Very well presented


Introduced in 1959, the Triumph Bonneville T120 marked the inception of a highly successful line within Triumph's esteemed motorcycle range. The Bonneville series is undoubtedly one of the most renowned names in Triumph's lineup. It underwent several notable changes along its journey, such as a significant ignition system upgrade in 1967. Notably, the 1968 model falls into the category of pre-1971 designs featuring the classic twin-loop frame. This particular design is often perceived as more coveted by enthusiasts compared to the later oil-in-frame models.

This beautiful example has been the result of an extensive restoration which was completed in 2018. The restoration saw the Triumph fully stripped back to its bare bones before having every part inspected, replaced or refurbished where necessary. The result is a restored 1968 Triumph Bonneville T120 to full UK specification.

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.


Car & Classic 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 £9,999 £100.00
£10,000 to £49,999 £250.00
£50,000 to £99,999 £500.00
£100,000 + £1,000.00

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.
