what pre 70 scramblers are out there, that may be available for sale or what to look for to race.
-
Didn't you have some pre 70 bikes which you sold eg a Husky and a Greeves - maybe you should have kept one?

That'll probably be the same guys who have been listing stuff on ebay us lately, things like new twinport head & drum/sprocket for the 69ish rear wheels
-
Mx 250, that is your though, but you are right, pre65 pre70 is the start of the true spirit of our sport and we need to talk about this era of machines it was a good era.
-
maybe you should have a thread about pre '70's Hardly's - that should get tongues a wagging and fingers a pumping ;D.
-
have a 69 250 husky coming over
-
Find me one of these please :)

. It's pissing down outside so I've had to come back inside so I'll take Daves bait ;D.
I reckon the pre '70 class is the most under developed class in the sport right now. On a dollar for dollar basis you have more chance to build a competitive bike on the el Cheapo than any other class. A smart operator can build up a DT1/RT1 or TS Suzuki for around 2k that would be as competitive as the sidepipe CZ or square barrel Maico class favourites. For those pre 75 or pre '78 racers looking for an extra ride you could do a lot worse than getting into pre '70.
Although side pipe CZs, BSA B44s and trick framed bikes still go for serious money, square barrel Maicos go for much cheaper prices than the radial models but the performance difference is minimal. I've raced in and later concentrated my efforts into that class since 1988 with my beloved 350 square barrel Maico and 250 DT1 Yamaha and will front up next season with two, maybe three new pre '70 class machines. For racers who see the pre 65 class as too expensive or intimidating, pre 70 is perfect for connecting with an earlier period without riding bikes that are dissimilar to pre 75 tackle.

Mark is write, l started racing in the late 1972 only because my big brothers said so, so pre 75 was my era, from 1963 l was going to scramble meetings with my brothers and being part of that era l relate to it better and enjoy the bikes a lot more, l think it was the true spirit and era of what we are achieving to day. pre 70 bikes are much more interesting.
-
I built this bike for really small money after Geoff Eldridge dared me to build a tricked up competitive pre 70 class DT1. The bike turned out to be far more competitive than I'd imagined with Kevin Flood coming within a metre of beating Boagy ahead of a quality field at the first Cherrabah Nats.
I rode it for a couple of years on and off and it's the bike that cemented the belief in me that once some sensible improvements are made, the DT1/RT1 engine is as good (or better)as any other two stroke in the pre '70 class. Even though my frame is radically modified and damn heavy, it handled reasonably well. Nathan, Vandy and others have found the potential these things hold and the best thing is that you can still find them for under $500.

No....I can see 'em all.

mark, your yamaha looks good., l think the dt 1 is under rated,
-
we ran our last meeting for the year at harrisville ,i think we had 7 pre 70 bikes on the line just appear to be growing
-
l think the dt 1 is under rated,
Yeah they're under rated Dave but we have to be honest and admit that you have to to quite a bit of tweaking to get them race-able. From the factory they don't have a hope in hell of competing on a level playing field with THE pukka race bikes but that's OK though as building them is part of the fun anyway. Fitting a frame lowering kit, upgrading the suspension by fitting decent forks (Betor, Ceriani, Maico, CZ) or cartridge emulators (PD, Gold Valve) and the shocks of your choice, you're on your way. After that you can go all out like I did by changing the steering rake, lengthening the swingarm, fitting lighter wheels,modern spec pipe, port job better carburetor....and so on, or keeping it basic. It's all down to your commitment and/or how much you want to spend. Whatever way you go, I reckon a well set up DT1 looks the ticket. I'm old enough to remember around 10 or so of these on the line in any given race circa '70-71. Here's a sweet '71 DT1 GYT/MX

Paul, take the fabric off the trampoline behind your Mako and use it for a trailer tourno cover, use the steel tubing for bike stands or something and do it before any little kid gets on it. cheers pancho
-
Not wanting to turn this thread into a Yamaha trailbike conversion thing but i'd agree with Firko in that the DT1 can be a good thing. easy to modify, easy to get parts and lighter to throw around than it's RT1 big brother.
i presently have a DT1 project bike on ebay for sale at the moment with the frame/swingarm mods Firko's mentioned already done.
to add to Shorelines comments, the BMCC pre~70 scene is steadily looking better too. it's a fun class for sure.
here's a pic of my Yammy RT1. she's a wild ride :)

I reckon they handle fine, really not much differant to the MX250 but more fun
Love mine, totally idiot proof ... ;)

you could do yourself a nice twin for pre 70. hondas little Rickman beater ???

-
That's sure a fugly little thing Marc but it's got a certain cool factor I reckon. I dunno what frame it is but the engine fits into pre 65. I've got a 305 that briefly lived in my Cotton frame when I had the ''brilliant'' idea that it'd make a pre 65 contender. I eventually sobered up, put the frame's back in the shed and the engine back under the bench. Yetman made a very cool frame for the engine but they're rare and expensive.
-
pre'70 is a little before 'my riding era' but it appeals to me simply because if you wanted to race a jap bike back then it was a converted traily and little else ;) that is unless of course you had 1 of them thar TM250's with the twin straws or a Kawa F21M as pictured by E74 8)
my pre'70..I really must ride it one day but at 5000lbs and me being the 100lb weakling I don't think it's going to be a lot of fun :D I should drop it down (further!) for flat track where the wheels don't have to leave safety of the ground ;)

Vandy your RT1 looks great. I found that fitting a 21'' front wheel was a great improvement on mine.cheers pancho.

Yummy ..... I was waiting for B44 to be bought up as option. Make mine a methanol burning Cheney with titanium bodied rear shocks thanks ;)

The engine is pre70 but the rest looks to be pre 78.

I guess the frame pre 75 mate, stamped in the frame and they were Eric Cheneys dying words.... "tell Marc it is pre 75" .... anyway it is built for all British days and last time I looked it was all British.....
Shed art mate, best scrutineered with some mates and a Carona in hand. ;D
-
Has anybody ever set up or raced a triumph tiger cub 200? they can even run in pre 65.
I know, it's no methanol burnin' flame throwin dragster........but they look lightish for the time and for a weekend warrior like me probably heaps of fun??????

Couple of kids raced Tiger cubs when i was a junior , I think one was in a husky frame and the other possibly a Rickman Petite frame.
They went suprisingly well against the 125 jappers and euros of the day :)

marc fx, is that your cheney, it is a very nice bike and Eric was ahead of this time with his work
-
just found this thread, as a confermed pre 70 yamaha tragic I agree that its a fun class .I started at heaven on a dt1 no mods even a 19 inch front ,circled at the blunt end of the pack but always have a smile on the dial when i ride it . I was the winner of vandys ebay dt1 ,so I now have 4 dt1s 3rt1s tragic is not the word mabe obsessed is .
-
I have a real good feeling that pre70 classes and pre65 classes they will take off in numbers a lot better, if collector will let go of the reins, You don`t get the die hard Trophy hunters, you get enthusiast that love this era.
-

Yeah actually the more I worked on assembling it the more I notice the nice bits, like neat place for the battery, rear guard lower in alloy and the fit of everything is really pretty good, it all lines up nicely. Just need to get the sidecovers on, fill the battery and it should light up ;D
-
Nice bike. Is it Pre 70 or Pre65?

Probably pre 65 as long as the hubs and forks are pre 65 legal but I'm sure I'll be challenged on it. Pre 70 for sure though.
-
Thats a nice looking bike NSR.....would look better if he didnt try to make it look like a 73 CR Elsinore....polish the tank, get rid of the sidecovers, put the front guard down on the wheel, easy to do and then it would look more "era"....does he ride it?....still pretty cool.
-
Pretty bike, but I reckon if you add up all the pre 75 parts on it, you'd have to say its closer to that class. Certainly wouldn't be a light weight with a 305 motor though...I tried lifting one I had once.
-
He has certainly done a very nice restoration on the bike.
