SuperTwins Challenge Cup Round 1

Just over a week before the first round of the “SuperTwins Challenge Cup” on the 10th of June so come and join the party. This event is for the many and not the few and will require strong and stable nerves to get in the final. A conservative estimate is that there will be at least eight competitors of varied experience from green to seasoned riders. Each independent rider will complete 3 qualifying runs and not to labour the point must be in the pairing lanes when called by the elected NAST member although we are quite liberal with the times. Eliminations will begin soon after so u have no time for a short kip (groan).

Whatever happens on the 8th you can be sure of a good weekend and leave the politics at the gate.

Mike Nelthorpe’s Polaris Project

New Twin on the track at Santa Pod ‘Race, Rock&Ride’ event for shakedown and observed runs will be the Polaris 2-stroke powered machine of Mike Nelthorpe. A very unusual project that has taken several years to complete after it’s conception by Pod scrutineer, Les Harris. It is based on a snowmobile using drive belts and not gears and beautifully clothed in carbon-fibre created by Sylvia Nelthorpe in their H.Q. Fibre Products workshop in Norwich.

10th annual MSA/ACU APIRA Springspeed Nationals UK Drag Races

After the first and second rounds of ETB/NAST at Santa Pod, with its new status as a National Championship, it was all move to Shakespeare County Raceway for round 3. Unfortunately due to insufficient entries at these meetings the Gas class has not been run so far.

With the SP events being dominated by Phil Pratt and Gary Hester we were denied the spectacle of this pair fighting it out again as Phil was missing from the entries. Chance for Gary to add some much needed points in an effort to catch up. With 15 entries as round 1 there were a lot of points to be had.

Many racers had arrived on Friday to enjoy the pleasant but cool conditions and leisurely prepare for the first day of qualifying. For NAST the Moors were in force, as always, together with Mike and Sylvia Nelthorpe with the Aprilia before debuting the 2-stroke monster Polaris at ‘Race Rock and Ride’. Dave (the hat) Smart with the recently lowered Suzuki TL and Robbie Dobbie on his revamped Honda SP1 were joined on Saturday by NAST Gas champion Alfie Udall who again found himself in ETB due to lack of Gas entries. Leo Lester also arrived on Saturday with his R6 and a Suzuki TL in the back of his new race transporter together, surprisingly, with his wife despite the expectation of giving birth sometime in the next 8 days! Usual Twin members missing for various reasons were Peter Harrison (new job commitment and lack of transport), Chris Mott (impending house move so everything in boxes), Tim Boutle (in America) and Simon Clamp (in France).

First round of qualifying saw Gary Hester in number 1 spot but a surprise 2nd place to Robbie who, together with Alfie, had been moved to ETB/NAST. Alfie was struggling with a new setup and an expensive gearbox rebuild after an awful lot of damage after his last outing at the Pod. In session2 Gary was pushed into 4th place and the Moor’s were starting to make good with a 2nd place for Giselle. Before the 3rd qualifier could be run the track was on hold for a cleanup. Not fluid this time but lead shot! almost the length of the strip a junior dragster had deposited a tube of the small objects after a cap had come off. Damn and ballast, our 4th  session was looking doubtful but we did get to run a third despite another delay while the cause of a total lack of power was investigated and all the computers had then to be rebooted. A quiet evening followed as the band in Kenny’s bar did not appear. It was also time for Leo to disappear as his wife did not think an airfield a suitable place to bring her next child into the world (their son was born the following day and all are well – congratulations).


With quite a strong but warmer side wind we were out at 10.30 as the 4th qualifying session had not been completed on the previous day. Yvonne and Chris Mott joined us for most of the day as spectators. Again Robbie surprised everyone (especially himself) by claiming number 1 spot with Alfie sorting his problems in 4th and Dave (the hat) keeping the front wheel on the track for once in 5th. Only one more qualifying session for ETB/NAST due to delays caused by an oil-down, several blocks taken out by a car crossing the centre line, another car wiping the barriers at the top end and of course, being a Bank holiday, the inevitable rain which eventually finished the day’s activities about 4pm.


After heavy rain overnight it was not looking good for the eliminations. The track crew valiantly began drying the track only for a shower of rain to destroy all their efforts. Again they got on with the job but now an even heavier shower followed by hail left the track in an even worse state. However they were not going to give up, and despite a few racers leaving and many more packing up and thinking that it was only a matter of time before the event was called and time to leave, the strip drier was fired up. It was now a desperate effort to get ready for the first round of eliminations which were run at 3.45. An amazing effort by the track but it was not to end there. After running most of round 1 an oil-down the length of the left lane should have signalled the end but no, out came the crew again and before the 5pm curfew we were running again. The shutters finally came down when almost at the end of round one the out of shape ‘Jap Series Pro’ car of David Greenhalgh almost took out his opponent in the opposite lane and ended in the Armco barrier. Reluctantly we all packed away for the second time that day and made our way home in the sunshine.

Phil Pratt still leads ETB with Siobhan Moor number 1 in the NAST championship. (Despite having more points than Siobhan Alfie’s Gas ‘bike does not comply with ET construction rules (subject for AGM) but he is currently 7th in ETB).

Next round is ‘Race, Rock and Ride’ where again there is a very healthy 16 ‘bike field, unfortunately insufficient Gas entries again so Mike Nelthorpe on the Polaris is relegated to ETB/NAST.


Don’t forget SuperTwins Challenge Cup – first round soon.


SuperTwins Challenge Cup

SuperTwins Challenge Cup Series 10th June, 8th and 22nd JulySeriesBanner

 But what’s the ‘SuperTwins Challenge Cup Series’ all about?

This special one of a kind ET Bracket is open to all street legal or race ‘bikes. It is intended to run a minimum of 8 vehicles at Shakespeare County Raceway on Saturdays of RWYB weekends.

If you are riding a Twin-cylinder machine you will have, free  membership of the National Association of SuperTwins (NAST) at the first round in June and automatic entry to the series with trophies and prize money of £250 for the series winner and £100 for the runner-up.

How does it all work?

ET Bracket Racing is a handicap race which gives the slower vehicle a head start. The difference between ‘vehicle A’ starting first before ‘vehicle B’ is determined by the difference of dial-in times by which each rider writes his ET on the rear of the vehicle (you will get an idea of your dial-in time during the 3 qualifying sessions). For example rider A may dial-in a time of 12.50 seconds and rider B a time of 13.30 seconds. A quick calculation reveals that rider B gains .8 of a second advantage at the start from the activation of the green light in his lane only. Rider A after the amber count-down and the activation of the green light in his lane has to catch rider B to win the race thus making for close competitive racing at the finish line. This is why it is important to get a good start. However, neither rider may run quicker than the time with which they dialled in because to do so would mean instant disqualification during eliminations (known as a ‘Breakout’) giving the other rider the automatic win to the next round. If both riders run quicker than their dialled in times then the winner is determined by the rider who broke out in the least amount of their dialled in time. Another form of disqualification is a foul start (or Red-Light). This happens when the rider reacts to the ‘Christmas Tree’ too quickly and rides away from the starting line before the green light.

Should dual infractions occur, say a red-light and then a break-out, the red light would be classified as the worst infraction. Crossing the centre line is also instant disqualification. It’s as simple as that. If you need more information see any of the NAST riders (SET or STG prefix on race number) who will be glad to help.

Event Format: There will be three rounds of qualifying (dependant on time) for those riders taking part in the Gamblers race followed by either 4 or 5 rounds of eliminations dependant on the field size. Those riders who don’t make the field, sorry but that’s part of the Gamble but you will be able to use the track during the day and also after you have been eliminated.

Time Table: By 10.00 am all riders will be required to have been scrutineered and signed on. 10.00 am to 1.00pm – three qualifying rounds. In the event of a 16 ‘bike ladder being run then the first round will begin at 1.00pm and so on. Please listen to PA announcements and NAST members who will ensure you are in the pairing lanes. All timings are subject to change due to track and weather conditions permitting.

How Much To Race: In addition to the General Admission to the Raceway and the RWYB Track Fee of £25 (or £40 for the weekend) £10 buys you a place and a race number in the Bracket (if you can, print the form on this link, fill in and hand over to a NAST committee member, we will make ourselves known – look for the club banner. There will be blank forms available on the day). Your £10 will go into the prize purse for the winner and runner-up. Prize purse will be calculated on the number of riders but will be at least £100 (guaranteed by NAST at each round). Good luck and enjoy your day.

NOTE – If you have entered the NSA sprint on Saturday/weekend 8/9 July you only have to pay the Gamblers £10 fee to compete (but you will have to make sure you do at least one qualifying run).

AGM Feedback


Congratulations on Dave (the hat) Smart voted in as the new NAST Chairman. Peter Harrison carries on his role as Technical Officer and is also now responsible for merchandise. Yvonne Mott and Robbie Dobbie retain their current posts.

NAST Championship

With 5 meetings at Santa Pod and 2 at Shakespeare County Raceway it was decided that the 5 best results from 7 rounds would count towards the championship, no extra points for doing all rounds (see Race Dates page).

SuperTwins Challenge Cup Series

With 3 dates agreed at SCR and after a discussion on prize fund and trophies it was agreed that riders of twin cylinder machines would get free membership in June only if entering the series. NAST would guarantee £100 at each round but no trophies. After 3 rounds the overall winner of the series (NAST member on a twin) would receive a trophy and £250 with the runner-up also getting a trophy and £100.


When the NAST banner is returned it will be reinstated as the trackside banner at SCR for the forseeable future.


Tim Boutle proposed the first round of the championship next year should be in Florida. Unfortunately this was seen to be too far to travel at the weekend for most members.

With the APIRA Prize-giving due to start it was a quick trip over the road to the Hilton Warwick. Congratulations to all NAST trophy recipients:-
