1978 Yamaha TT 500


  • Rugged offroad fun
  • Comes with lift stand
  • Some spare parts including the original exhaust

The appeal

Made from 1975 to 1989 the TT-500 was the off-road version of the XT-500 street bike, utilising the same twin valve, single cylinder, four stroke 499cc engine. This bike was purchased as a purely off-road bike that was imported from the US state of California from a bike dealer in Warwickshire. The bike has been used mainly off-road on a farm, but the owner is downsizing their collection to focus on other projects.

The history and paperwork

The bike comes with its current owner’s receipt of sale, a parts invoice for some service items and a California ‘off highway’ sticker. The bike was purchased from Huggy’s Speed Shop in Atherstone for use on a farm and has not been road registered.

The Exterior

  • Rugged appearance but reported to be structurally sound
  • Small tear in seat leather but easily repairable
  • Aggressive off-road tyres

The exterior of the bike is a typical look for an off-road exclusive farm bike but also looks to have been cared for during its time and judging by the way the owner spoke of the bike they were clearly fond of it.

The bike is very much substance over style and that shows, if you want a show bike this is not for you but if you wanted a bike you could use all purposefully and not worry about scratching it whilst green lane-ing then surely this has to be one of the best purchases. 

The orange fairings are a little tatty but not broken or missing, the steel tank has a small dent at the front but is otherwise in good condition. 

The frame has some surface rust but it is reported to be purely aesthetic, the suspension is reported to be working well and no leaks could be seen at the time of the photoshoot, the same can be said about the engine in terms of operation and leaks. 

The bars and front forks look to be in good condition also with the owner showing their sense of humour with a bicycle bell on the front. 

The Mechanics

  • Twin valve, single cylinder 499cc, 4 stroke engine
  • 5 speed transmission
  • 21-inch front wheel and 18-inch rear 
  • Straight through exhaust

The bike started well and drove as you’d expect, it looked to be very controllable and predictable off road as the bike was driven from its barn to the lane, we were photographing in. 

The engine sounded strong and healthy with the owner reporting there to be no known issues with the bike. 


Any off-road bikers will know of the Yamaha TT-500 as it had successes in the African rallies that saw a rise in the late seventies, the Paris-Dakar rally being one of the ones the Yamaha came first in, for a farm bike this might be a little overkill then but if you’re wanting a hugely capable off-road machine then this example surely warrants your attention.

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 Commission bids?

A commission 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.
