The Appeal

It’s the early 70s and you’re standing on a street corner. In the distance you can hear what sounds like an incoming bombing raid. You’re a little alarmed. Suddenly, hoving into view, is a motorbike, its chromework glittering. The handlebars are twitching as the rider wheelies wildly down the road. 
You’ve just seen Kawasaki’s H1 Mach III 500. Even the US importer nicknamed it the widowmaker. And with good reason. Kawasaki set out to create the fastest and quickest accelerating bike ever built. It succeeded, albeit at the cost of a few visually dramatic wheelies. That was due to the heavily rearward-biased weight distribution. 
The H1 didn’t quite have the handling to match the performance, but it hardly mattered. It sounded amazing, it went like stink and it looked great. 
All characteristics we are helpfully reminded of by this beautiful ‘71. Recently imported to the UK, it looks as if it just rolled off the line in October ‘71. A matching numbers bike - details are verified by the Kawasaki Triples Club GB - with recent fettling by specialists, it runs and rides as good as it looks.
Few bikes were as exciting as the H1. And this is a great example.

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.

Anti-sniping

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.

Pre-authorisation

We may hold a pre-authorisation charge on your card until the end of the auction when the hold will be cancelled. If you win, we'll take a security deposit which counts towards the payment for the vehicle and isn't any extra cost to you.

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.
