I am after some info /advice on what would make a good pre-75 125 race bike.
Is it all Honda?
-
hey Bill,
if you'd like to run at the pointy end then the Honda's seem the go but the more time i spend with my little Yammie, i'm in love with it.
i havn't had the top end off it in a bit over a year and she just keeps on going.
i've never riden a CR or TM but i reckon any of them well sorted will treat you right.
the TM,s do look cool though.
-
I haven't ridden a Honda, but I have had a couple of laps on Vandy's bike and I have to agree it's a fun bike to ride
-
Hey there Michael and Mainline. Congrats to Vandy for the podium finish at the Nationals.Well done.
I am thinking about off-loading one of my more modern VMXers for a pre-75 bike. It looked like a lot of fun and I could go into some age- grouped races. If I had a choice I would like some low to mid range motor more than a top end screamer - I know it is a bit of a tall order for a 125. I will do a bit of research into whats out there and hopefully get something for next years Nats at Broadford
-
An mx125 would be a good choice for a broad power band.

The Honda is the bike to go fast on, primarily because it has the 6-speed box and goes well.
Its also a tiny bike and one that's relatively difficult to get along with.
The YZ-A is about as fast, a heap easier to get along with and is more comfortable to ride, but is hindered by lousy forks and a 5-speed box. The MX-A (or even DT125A) can easily be upgraded to YZ spec (or better!) and are a shit-load cheaper to buy.
The TMs are somewhere between a stock MX-A and YZ-A in performace, as far as I can tell (I haven't ridden one).
The KXes are supposed to be close to a match for the CR, but they're a rare bird, so its probably academic.
Personally, I own a YZ-A, MX-A and a DT-A.
The DT is the race bike of choice because I couldn't see the point in butchering a rare and relatively valuable YZ to make the same race bike as I can by using a freebie DT.
Its got a YZ-A gearset, ported barrel, YZ125J pipe, 32mm carb & CDI from a YZ125E, 34mm DT250A forks, YZ250B triple clamps, YZ125E front wheel, and a YZ125X rear wheel (same as YZ-A but takes flat rather than dished sprocket).
Its about to get a YZ125A alloy tank and a YZ360A seat and some decent rear shocks. If I was to start again, I'd do everything the same, although I'd doubt that I'd find another 360A seat, so I'd probably use an MX125A seat.
I think it owes me about $1500 and a lot of time in the shed. The price has been held down because I wrecked a $200 YZ125E, and because I've been patient/lucky enough to get a lot of 'fun parts' cheaply.
It is infinitely easier to get along with than an Elsinore - it idles, it pulls cleanly off the bottom and it doesn't load up. With a standard DT pipe, it was fast enough to challenge for the win in the Classic 125 class at Heaven level, largely through tractability that allows impressive corner speed.
I won't say that it handles brilliantly, but for a non-midget, it is predictable, vice-free and handles a lot better than a stock Elsinore.

Bill if you can find one a KX 125 is what you need :) they are as quick as a non dope CR but they pull from nothing and keep on reving.
They are a 6 speed and if you want them more peaky design a Skunk werks replica induction kit and fit a 34mm carb.
The forks are a bit sad but a 250 front end and some decent shocks will make the world of difference.
The YZ is a great bike but as Nathan pointed out that 5 speed ::)
TMs are great and parts a plenty but it takes a bloody good rider to put one at he pointy end of the pack ;)
Congrats to vandy ;D he rode a blinder in the last race and showed the potential of the MX 125 :) :)
-
A CR with a different Honda 125 cylinder will sort all of the above out ;)
-
Dont do it Grossi,stick to the kettles!!!! ;)
-
just out of interest how rare is something like a Mk.5 Bulty and how do they compare to the jappers of the era?
they certainly appeal to me but are they more trouble than their worth?? :-\

Good looking bikes arent they Doc, wouldnt mind a 250.
motors seem to be fairly agricultural but seem to work, like those Montessa's . But from what i can see in the states they have all the engine parts so shoulndt be a problem for a smart guy like you to keep one running.
-
mmm, they are 8)..always liked the early Pursangs Freaky but after having a real early Alpina that wouldn't pull skin off a custard and a mate having woes with the bulty he owned I sort of lost interest for about 20 years. For about the last 3 years I've been thinking of something different like a Pursang but I'd like a 125. Couldn't be any more ag than the CZ could it ???
-
Craig Schoone punts around his 125 Bully very well :)
-
Thanks for the heads-up Nathan and Bill & Doc etc. I think there is another project being born. I was just day dreaming over the HOLLOWAY 125 COLLECTION IN VMX. If anyone finds a 125 Phantom laying around just PM me!
-
If anyone finds a 125 Phantom laying around just PM me!
yeah, good one Bill,
if anyone finds a 125 phantom, i'd reckon this forum wouldn't know until it was tucked safely in thier shed.
what about the 125 TM Dodgee had for sale?
Suzuki27.... ;)
-
Having been on hols in unzud I'm a bit slow getting to this one. Surprised to see the Pursang get a mention, but Mk7 125 is a sweet bike, esp handling & suspension.
Reasonably light & stone reliable when built right. Quite easily get decent power too. Would love to see what Lozza could get out of one. Long stroke engine for 125
Mk7 125 g'box ratios are a bit closer than other pursangs. RHS shifting is a problem for many, but can be converted to LHS. IIRC Tim Weaver in US has won numerous champs on one. Altho it has a diff barrell, a Mk8 version won pre78 125 class in Tas a few yrs - pretty amazing feat when you compare a 75 'sang w a 77 RM or YZ.
IMHO, pursangs are much more than the sum of the parts.

what about this little beauty, light, very fast, handles.
-
A Can-Am 125MX would make perfect base also.
-
Hodaka combat wombat 125, very nice bike, something different
-
Lozza...the Can-Am 125 does not qualify for Pre'75...pity really 'cause that Rotax rotary certainly is quick...only held back by questionable handling and a bit overweight..
-

Hey Dave, Suzuki27 wants a 125, not a 185cc 250 class bike pretending to be a 125. :o
-
I have a '74 KX125 undergoing race prep now. Will be ready and available in a month or so. There are a couple of other brands in the shed as well, one just as rare, maybe rarer than the KX. Anyone interested can PM me.
Cheers,
K
-
Yammiefan, wonder why not they were made then but are not allowed in the MOMs only the 175 & 250?
-
Mark you must say at the time 40 percent bike and 60 percent rider
Come on Dave it wouldn't have mattered if Will Bauer was on board the bike. The bike was ilegal and shouldn't have been allowed off the trailer. You knew it and you accepted your trophy without a word and that pissed a lot of folks off. You're a good bloke Dave but you cheated that day and you can't justify it by saying you didn't know. My Kiwi mate Bazza spotted it in the dark 10m away while half pissed. ::)

this model montesa 125 mx was my first bike l bought and raced
-
Hey guys. Haven't you read the FIM rules, MX2=125 2 stroke and 250 4 stroke. If you can race a modern high-tech 250 4s. against the modern 125's, you should be able to race an old heavy trailbike 250 engine against the old 125's, the 2s. are almost the same then and now. ;)
-
Carn't they run the 150 kit's on the 125s to make them more even?
-
thats just swearing, if a four stroke can't match similar opposition best bet is to burn it and buy a two stroke. Ak least, thats what Lozza tells me :D
have a look at bucket racing on the road and you see what shit happens when you start trying to make different capacities comparable, one bloke spends thousands of hours and dollars to build a unbeatable bike to fit rules he made the framework for so that a four stroke can get a win against cheap cr85's

Still got my bucket for sale if you wanna go racing on the tar ......... might even throw in 3 more motors and a large parts kit, keep you going for years :O)

Mk.5 Bulty and how do they compare to the jappers of the era?

You got us again Alli.

yes sorry !! I should of added a bit extra from UnZud.... ;) ;D
125 real mens bikes;
I'm here to tell you, that there isnt a more thruthful statement than the subject that we are debating tonight. Oh yes, the other team are going to have you believe that a 125 is just a small tiddler of a bike. It doesnt go fast. Wheres the power!!! No grunt!!!! And YES all of it is true. But and I do mean BUT. We aint here to debate the bike. We are here to debate if real men ride 125's. And the answer is YES!! And the opposition know they havnt got a crankcase to argue. Thats why they will try to attack the bike... They will try to have you believing that a 125 is a pussys bike, for juniors, not a real mans bike. All these guys know what it is like to ride a 125.... now they ride big bores.... And of course they would never go back to riding a 125...... and why !! Its to small, no power.... NO.. Its simple...... They know how hard it is to ride one......... not to let it bog down..... to keep it on the boil..... never miss a gear.. Sounds hard ya.... not like havnt low down grunt to keep ya outta trouble. Or enough power ta just ride through the rough stuff.... No ... there is none of that on a 125...you have to ride the bike..... your the real man doing it... Thats why these guys dont wanna ride a real mans bike...... its to HARD.. They need there low down grunt. They dont wanna change gears any more. They want the bike to do it all for them. Is this a real man!!! NO....... Real Men Ride 125's ...Yes
I've said it before. Yes. Real men ride 125's...... And how do they ride them...... WFO..... Wide forking Open......Its where it all started.125 riders do everything hard..... just ask there women.....coz they know..... If ya cant keep her screaming ,, Ya just dreaming. And its the same with there bikes.....There is only 2 places ya have the throttle. Off or WFO. No in-between. No middle of the road....No I can torque my way outta this.......... Lets look at that concept. Off ; On..... Off ; On....... No throttle control here, No rolling the throttle on.......No pussy footing around........ Just get that thing open. Open ; Closed ; Open ; Closed........ None of this action. Roll on ; Roll off ;Roll on ; Roll off ; Come on guys It kinda looks abit like ya having a wank!!!! No , 125's are real mens bikes. Ya have ta be fit. No arm chair ride here. Miss any of those 6 gears and that rider behind you is now in front of you. Lets face it, the old saying 'its not how big it is, its how you use it that counts' is pretty true. And all you guys on you big bores, well, I can think of another saying about that. Is it really true that riding a big bore compensates for smaller things else where!!! The older we get the wiser we get.. so we all think ....... Is that why older guys like to ride the big bikes because they are wiser...and know that its easier......Well real men dont care. They ride 125's...........Its that simple........ You either ride a 125 or your've gone soft. And that my opposition is where your at.. 125 riders dont wanna race against anything but true motocross bikes....... Therefore its the rider that has to do the real work to win.....And this my fellow 125 riders I share with you the knowledge that you are the Real men of motocross....

Hi
You are right about that , they might be light, but they are bloody hard work , total concentration is required , just one small mistake , and five guys go past you, all the fast 125s have about the same power,so trying to catch them back up is hard work, dont use the brakes, it just slows you down,
I would love to see the fastest 20 guys all on CR 125's, what a race that would be.
cheers
-
If winning is a major priority I'd suggest a nice '74 Honda CR125 for sir. If owning something cool is more important than collecting trophies, I'd reccommend a nice Rickman Zundapp Micro Metisse. If you want to combine winning and being cool it's hard to go past a Monark 125MX or perhaps a nice little Maico 125.
-
The Lewis Penda in my fav pre 75 125 the combination of cool and Honda power.
