Whitehawk Ty80's

The Whitehawk ty80 was developed in 1979 by Mick Whitlock at his factory in Horndean in Hampshire. I remember visiting Micks shop/factory when i was a kid back in the 70's and 80's. Mick bought out a kit for the original ty80, comprising of : Chrome plated frame and swinging arm manufactured in Reynolds 531 tubing, complete with spring loaded footrests, brake pedal and rod, stronger tensioner arm, alloy sump shield and swinging arm mounted prop stand.

This gave the ty80 improved handling, longer wheelbase, more ground clearance and a higher seat height. This was the Mk1 Whitehawk with tank having black top, gold pinstrip and white bottom, chrome seat base, exhaust shield and black side panel. The very first ones biult had tanks the same colour as the Beamish Suzuki.

Then came the Mk2 Whitehawk, same modifications as Mk1 but with a all in one tank seat unit in white fibreglass and red front and rear mudguards.

There was also a Mk3 Whitehawk but this was only made for a select few and only between 5-8 were biult, so very rare. This had 17 inch rear wheel and 20 inch front wheel, also a longer swinging arm to take bigger rear wheel. To take bigger front wheel there are spacers in top of forks to increase fork length.

Ian Pebery is the man to speak to about Whitehawk Ty80's. Ian is able to offer quality reproduction parts and custom designed performance parts he has developed, which have been tried and tested in competition. See Ians website and contact details from the link on our contact page.

We have a Mk111 Whitehawk that we are restoring at the moment. It came to us in fair condition but is having a full strip down and being restored back to original.

Whitehawk ty80 mk11 ready for restoration.
