The

 

British Rival

 125 Competition Motorcycle.

 

 

This is the motorcycle breed created by Midlander Ken Sedgley.in 1977.

Ken himself was and still is a  top rated Trials And more so Scrambles rider.

Also a ISDT rider for Britain riding  Greeves  for one.

And has even been a racing driver in the early Seventies driving a Formula 3 Chevron B17.

The story of this bike as now become a whole lot clearer due to the input from Jon Harris who was in fact a works "British Rival" rider.

Here is  Jon's Story about the bike. and the vast album of photographs, that Jon has sent me is below. and they are his Copyright© but what great shots that record that thrilling time of School-Boy Scrambles.

Hi Charlie,
 
I remember seeing at various Shows Ken showing off British Rivals IN 1976 in white.
Know there were earlier ones possibly 1973/74 in blue.
 
1977 British Rival 125 was £800
1978 British Rival GP was £900, I may have had the only one sold.
Fairly sure the works 1977 was modified to 1978 spec, it had a longer swing arm and white/opaque mid guards. 
 
I did see an Enduro at ken's a few times powered by a 4 stroke 450 Honda engine. Think two were done, one was in another country not sure NL or Denmark?
 
Ken at the time lived south of Birmingham in Warwickshire, we visited a couple of times and had a small practice track nearby.
Ken used to hold test and practice days a various farms notably Kinlet, I have photos attached. Rob Andrews had a trial on one late 1977 along with Andy Jewkes both dismissed as slow and unreliable.
 
Mike Burbidge from Milton Keynes was sponsored by Ken to ride his bikes. Mike also had reliability problems and passed on the offer towards the end of 1977.
I pretty much took over late 1977 as one of the few still racing British Rivals. I used the works bike for Hawkstone Park New Years Day 1978 and bought one shortly after.
 
Biggest beef for me was lack of power in 1977 though quicker than the CR125 unchanged in years. Ken's' saying "make it up in the bends" never changed throughout 1978.
 
I had a mate when I lived in Sedgley West Midlands that also had a 1977 Brittsh Rival Andy Whiles.
 
Forks were made at Metal Profiles in Sedgley West Midlands, mine leaked. Rear shocks from Girling.
 
In short these 1977 bikes taught me how to ride and set the way I carried on riding thereafter. Many a time on certain bends you could throw it in that fast the bars would drop or foot rest pegs and exhaust bottom out, they were that good.
 
Come 1978 I may have been the only buyer having the GP125.
It was way way down on power compared to RM and KX so much so they could come out of a bend over take, enter and exit next bend before you even got there. 17HP against 23HP with the KX massive difference.
Despite a port job and eventually an over head exhaust EST 18HP it was as far as it could go but no match for the KX still. Problem being it became even more unreliable, barely could complete a meeting. Pistons were £44 back then and took 3-4hrs to run in. In race mode the pistons cracked at front of the skirt at sub 3/4hr! Another £44 a lot of money back then think average wage was around £34 per week gives you some idea plus travelling and entrance fees etc then a wasted journey.
 
Mid 1978 switched to Kawasaki KX125 A4 from RIP John Fereday when he ran Kawasaki in West Bromwich. Best bike ever had and still used it AMCA in 1979 racing in with 750's big difference.
 
Despite parting ways in 1978 I kept saying to Ken go with the Rotax engine. Being small scale meant he would have had to redesign the frames, change drive from right to left and rear drums etc.

4th and 5th had to enter and exit corners much faster to stand any chance of passing by 1977.
Next attachments were at the disaster ACU Schoolboy Champs near Brighton 1977. Gearbox selector meant stuck in 2nd gear.
 
I will send another email I have other piccies.
 
Glad to help

British Rivals Advert 1978.

This is our machine that we are so proud to have in our collection..............

 


Peter Cheethams Collection, Photo. 

 

These machines were built mainly to fill a gap in the schoolboy scrambles market.

But they were that good, they got used for the ISDT class as well.

The frames were commissioned from frame legend Eric Cheney.

These were very much like other frames Eric was building at the time, but built exclusively for Ken  with dimensions more suited to the scrambles bikes that they actually were.

A few good young riders at the time trying the machine had nothing but praise about the little machine apart from the gearbox that did have to many neutrals in the box and not good to find one of these going into a sharp bend.

The cutting edge of design about the little bike stood out with the sharp lines of the bodywork that could only be from that period of the seventies.

Ken Sedgley had ploughed a lot of money and pride into this machine, but that period like I say was difficult to finance anything and so we lost a brand of machine that was more than just a winner at that time but was an example to anyone that if you have a dream just go out there and try to fulfil it.

So we know the frames were good.

Engines used were the German Sachs, mainly 125 because of the class but the ISDT bikes may have been of a different capacity.

 

 

This is the ISDT   styled machine. used in the welsh three day as a test.

Here is a machine in ISDT trim, ready for the WelchThree Day Trials of 1974?

the bikes had the six or some say  seven speed gearboxes fitted and modified exhaust system.

Press get things wrong don't they.

Italian engine NO,it is not,  German,Yes.it is but some say Austrian too.

 

 

 

 

These cam adjusters were part of the Eric Cheney trade mark.

and the frames could have only been made by him.

I think the hubs are REH, and not Rickman as Has been suggested to me.

(Confirmed now Rickman).

I should have looked at my spare hub earlier, but it was one of the coincidences that happen on this site now and again. Mike Waller was going to use one this week end, and so I checked mine for him, and the Jon came along with his knowledge of the "Rival" breed and  we have two answers in one.

~~~~~~~

 

Not really a One day trials machine but it would be worth a try. just for the ride.

It is just a pity we don't have ISDT's any more this bike would be ideal.

The fork yokes on this bike are Metal Profile or REH. Legs and front hub could be Suzuki?

I have the MP 600 or Ceriani forks that could be fitted.

 

Here below, is the manufacturer Ken Sedgley riding his four-speed BSA Bantam in the Colmore "Revisitation" a couple of years back.

Here is a Photo of that same Chevron B17 Formula 3 car that Ken owned all those years back.

Ken or any of Ken's friends reading this, Jim would love some information on this car

Livery used at the time ETC. Just contact me and I can put you in-touch with Jim.

 OK back to the "British Rival" but it is a small world is it not.

The Boss, Ken Sedgley.

Here is the "British Rival" machine with Ken  sporting the  stylish nineteen seventies hair cut to match.

It is such a shame that these machines were not put into serious production.

With  the Eric Cheney frames and a Sachs motor that was good, but needed the gearbox sorting out with its seven speeds being of fine cut and said to have eight neutrals,

This probably its major fault, cycle parts were the ones used by most other British small volume manufacturers at the time and complemented the machine perfectly.

It was just one of those under financed projects at a time when backing was hard to come by.

I know I had the same problem with a project at that time.

02/04/2018,Update from Jon Harris.

Jon with air on the right.

A practice day with Ken Sedgley.

 

 
Have fond memories of riding those British Rivals equally the most frustrating over about 12 months I used them.
 
I did a Kawasaki training camp at Hawkstone in 1977 shared a tent with Mike Burbidge and Chris Morris for the week.
1st lap coming off the Girling leap broke foot rest off and handle bars dropped on to tank.
 
Constantly breaking the left swing arm bolt, from memory 1/2" x BSW the shear was on the thread total poor design.
Happened that often we acquired ken's screw extractors in wooden box, it happened that often and still use them!
 
After 36 years on I found some others that used British Rivals back in the day (1977.) Only know of 6 that used them apart from enduro's suspect only 8 sold and I had two.
 
I had the 77 bike and the last GP125.
My GP125 was later modified and fitted with an overhead exhaust welded, it was the only one to my knowledge perhaps 1/3 through 1978. No piccies but had to cut the air filter box out.
 
On your site the bike with overhead exhaust looks blown or may be from a jap bike modded to suit?
Front forks and hub definitely Jap and would have been changed since original build.
~~~~~~~
 
I had the 1977 and the 1978 GP125 at the same time during 1978.
One two day meeting in practice the crank sheared and fly wheel held in by the cover.
Subsequently my 78 bike had my other 77 engine in it.
The 77 bike would have had no engine when we got rid of the thing.
Had Bel Ray stickers on fork legs to hold a bit of oil in.
Rear shocks on the softer side would only distinguish from all others along with a welded up left foot peg.
 
Haven't seen or spoke to Ken since 1978, heard he was selling oils some years back.
I am still in contact with a 1977 buyer of a British Rival Andrew Whiles, he moved to the less rare Maico for 1978 with Rob Andrews.
 

British-Rival GP125 1978 Testing new bike at Kinlet.

In piccies above those were the red white and blue leathers that Ken bought me for Christmas 77. Had my name on back and British Rival in Red down the white strip, duly ripped off when I jumped ship.
~~~~~~`
 
Broad Street Birmingham rings a bell where they were assembled, knocked down decades ago in what looked like an old back to back terraced house from Peaky Blinders.
 
If I come across any further info I will let you know, feel free to nick the photos do as you see fit.
 
Keep me in the loop.
 
Happy to help,
Jon Harris

Charlie~Oo> Thanks Jon you have made this page, and given us a great insight to the foibles of the British Rival.

The finish of the frame is typical Eric Cheney ,Just First class.

(shame about the left-hand spindle bolt,letting it down slightly.)

I think by looking at the fork yokes they "Metal Profile" with air damping, that was the in thing at the time, and developed by a Guy from Banbury for his son Alan's Schoolboy bike 

Wilf Jennings.

 

Photo "Otterman".

You just get a glimpse of the quality of the bronze welding of the Cheney frame on this Steering head. Frame Number "008"

 

Photo. "Otterman"

Note that this bike is fitted with the wide finned barrel, still doing home work on these motors.

Here you can clearly see the engine type and cc 124 on the engine plate ,this is the spare motor mind.

 

 

 

These motors certainly didn't spare on the finning did they. but the motor was good,(although we now know underpowered against its "Rivals") it was the gearbox that was problematical.

The two bikes above are Cheney Scrambles bikes specially built for The Fisher's by Eric Cheney, Two of about 25 that Dale's Father imported to the USA, and was distributor for the product.

Dale still has a good collection of these machines and is always collecting others as he finds them.

You can see how close the relationship to the "British Rival" frame these are , well they would be, because the first Cheney frame built for the Fisher's was in 1972, so they were the guy's that had stood the development work of these frames.

 

Much More Later. with a report of how the bike rides.

~~~~~~~

 New material now arrived , on later. and the story.

~~~~~~~

Jon also sent me evidence that there was indeed a Honda powered British Rival in 1979 if I have it correct, and this too was with the cooperation of Eric Cheaney.

This was at about the same time as Ken started driving the Chevron racing car, and what I can make out, this now had priority over the remains of "British Rival" shame, but the times were moving on then, and change was the nature of the game.

 

 

The last of another "Britsh Brand".

I now have photos and information about a bike currently being used in Classic MX fitted with a CZ engine in-place and it looks as if it is a winner.

I am having a problem getting these onto the page at the moment but we will get there I am sure.

Photos later.
