A brand new concept in shale racing 𒀰will be unveiled at Coventry on Sunday when ex-speedway stars Andy Grahame and Arthur Browning give a first public airing to the Motoslide machine!

They are the brainchild of four-times World Speedway Champion Barry Briggs who h🎃as working on the project since the turn of the century.

He has developed a convertible kit that can transform a conventional moto-cross bike into the speedway hybrid and will be ridden publicly for the first time during the three-hour Briggo'd Extreme Races at Coventry Stad🎶ium on Sunday (Septemꦫber 15, 3 p.m.).

And if suc♒cessful they could precipitate the launch of a brand new stadium mot🍬or-cycle sport attracting riders from both moto-cross and speedway.

The🐬 concept behind the ꦐnew machines is simple - making it possible to slide a moto-cross machine around an oval, shale circuit and the conversion kit will be relatively cheap to buy.

Briggs said: "All mo🐈tor-cyclists, whether they ride on the road or race in fields, want to slide because it's one of the big thrills of riding a bike but speedway is the purest form of slid🍬ing there is.

"But speedway rꦛiders are hard toꦺ come by, you need special techniques to ride a speedway bike and that takes a long time to acquire.

"Generally riders can slide their moto-cross machines but they are not made to slide easily and while they can slide a littꦐle way they then throw riders off.

"I figured with a🌳 few refineme💖nts it was possible to have a bike that could be used for both moto-cross and a form of speedway which is where the MotoSlide bike came in.

"You have got so many riders with mo꧙to-cross bikes laying in their back sheds♒, to ride moto-cross you have got to beat hell out of your body and a lot give up because they can't carry on with the physical demands.

"I am sure a 𓃲lot of those riders would fancy taking up speedway if they could still use their moto-cross bikes, with a few adjustments. What I've come up with is a very cheap way of turning a ಌmoto-cross bike into a slider - and vice versa.

"I have been working on it for two or three years. That's how I first met Coventry's Ryan Fisher, he came out to a lake in California when I was testing it. I've now got two machines b𓆏uilt up - a 250 c.c. Yamaha and a 426 c.c. Yamaha."

Former England international Alan Grahame, who started o🐎n moto-cross, turned to speedway and is now back in moto-cross competing in British and World Championships with a sidecar, will 💞ride one of them.

And🥃 one of Britain's top all-round motor-cyclists, ex-Birmingham ace Arthur Browning, a former speedway ride𝔉r who is still very successful and a winner on moto cross will ride them in a series of moto-cross races as part of Sunday's meeting.

"There will be 10 or 12 riders in the races along with our moto-sliders and it will be a tremendous and competitive test. We have trialled the bikes extensively but always b🤡ehind closed doors and th💝e general consensus of those who have seen them is that the spectator will notice very little difference from the conventional speedway bike.

"The most exciting aspect is that th𝄹ey open🅺 up the door to having up to ten riders in a race that can be seen every inch of the way. It's a compromise between the dozens who can race on a moto-cross circuit where much of the action is out of sight of the fans at any particular vantage point and the conventional four riders a race in speedway."
