1980 Kawasaki Moriwaki ‘Monster’ Racer


• Built to the original spec by Gordon Pantall
• New replica Moriwaki frame
• Only ridden for 6 laps of the Jurby Festival in 2019
• Extremely rare, race-spec bike


When it comes to motorbike racing, the Isle of Man TT is the absolute pinnacle of courage and talent. And the riders and machines that succeed there are the stuff of legends. Alan Jackson, an IoM TT winner, rode the Moriwaki ‘Monster’ (based on the Kawasaki Z1000) to 4th place in the 1980 race.

The bike was sponsored by Gordon Pantall, an ex-racer himself, and built from Moriwaki frames imported from Japan. Only one was imported, so it is a incredibly rare bike.

Gordon Pantall was the only one to import a Moriwaki kit into Britain in 1979, and four replicas were born from that kit. For those unfamiliar with the bike, Moriwaki are a Japanese engineering company who have specialised in the design and creation of high performance parts for motorcycles and cars since the early 1970s.

Mr Pantall had parts for the bike in storage until he retired, when he decided to build this full, original specification replica. He completed this in 2018, and the bike was displayed at the 2019 Jurby Festival where it completed six demonstration laps.

The bike has never been raced and has been dry-stored since completion.

It should be noted that this is a track bike and has not been registered for the road. As such, there is no V5 or service history. The owner has built the bike himself over a number of years, after having stored and collected the parts over many years.

All of the bike’s external elements, from the frame and fairing to the seat and handlebars are in fantastic condition. It presents as a fully restored, original 1980 TT racer.

No expense has been spared in building this bike, and a wealth of new and restored original specification parts have been sourced and installed, making the bike look every inch the period racer. These include:

  • Brand new UK made replica Moriwaki frame, made of bronze welded Reynolds tubing
  • Frame and swinging arm powder coated in gloss black
  • Refurbished Dymag wheels, new wheel bearings and new Avon Race tyres
  • New fibre glass replica fairing, seat and front fender
  • New alloy Moriwaki replica fuel and expansion tanks
  • New Scitsu electronic rev counter

Finished in period-correct Moriwaki blue and yellow livery, the bike is a stunning recreation and in almost showroom condition.

Mechanically, the bike has been built as close to original specification as possible. Mr Pantall has used new or high quality refurbished parts throughout. He assures us that the bike runs perfectly.

The frame was built to accept a twin-shock or single-shock set-up at the rear. It currently runs the twin-shock set-up, as per the original 1980 racer.

The list of parts used in the build is extensive, but includes the following:

  • New box section swinging arm with needle roller bearings and aluminium chain adjusters
  • New Hagen rear shocks with spring/damper adjustment
  • New Moriwaki/Kyaba front forks and yokes
  • Refurbished AP Racing callipers and master cylinder
  • Kawasaki front floating discs and standard rear disc
  • Refurbished Z1R crankcases
  • Moriwaki 998cc 10:1 pistons
  • Moriwaki spec new replica F1 race cams
  • Gas-flowed cylinder head with large inlet and exhaust valves and H/D valve springs.
  • Under bucket shim arrangement
  • Standard Kawasaki clutch assembly with bearing release mechanism and H/D springs
  • Kawasaki Z1000 carburettors with velocity stacks
  • New oil cooler, pipes and fittings
  • New Dyna ‘S’ electronic ignition system
  • Engine filled with 10/40 Mineral Race Oil

As can be seen from the specification, enormous care has been taken in creating this replica, and the level of craftsmanship on display is wonderful to behold.

If you’re a fan of motorbikes, and especially if you’re a fan of the TT, then Moriwaki is a name you’ll know well. The Japanese engineers are renowned as creators of high performance motorsport parts. So the opportunity to get your hands on a full Moriwaki replica – especially one with the provenance this bike has – is not to be missed. 

Gordon Pantall was a racer in his own right, before going on to sponsor a race team, and this is a spot-on replica of Alan Jackson’s 1980 bike which came 4th in the TT. You simply won’t find another one of these anywhere else. Hand-built by Gordon himself to the very highest standard, its a genuinely incredible machine. 

Of course, you need to remember that this is a pure racer, built for the track and intended to be used there. They weren’t called ‘monsters’ for nothing, and this is certainly no road bike. But it is one of the rarest, best engineered and prettiest racers we’ve seen in a very long time. The Moriwaki livery has always looked great, and here it’s presented in as-new condition, making it the kind of bike that would be the highlight of any collection you care to mention.

It may well be a monster, but this is one monster we’d really like to take home. We’re not sure it can be tamed, but we’d definitely be willing to take our chances…

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 5-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 below the reserve price you'll bid that amount if you are the highest bidder.

If your maximum bid is above the reserve and you are the highest bidder - we will only auto-bid for you up to the reserve price.

Once the reserve has been met, C&C will make sure you are the highest bidder using the bidding increments stated below, keeping you in the lead up until your maximum bid OR up until just below your maximum bid when the increment value would have taken you higher than your maximum bid.

Once the reserve has been met C&C will make sure you are the highest bidder using only the bidding increments stated below, keeping you in the lead up until your maximum bid OR up to the next increment closest to your maximum bid if your maximum bid isn't enough for the increment value.

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

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.
