One question though.. The early ones were more powerful than the later ones due to learner laws. Does that mean that the later ones are de-tuned or simply restricted? |
De-Tuned.
The Twin-Shock CB125T's had a claimed 17bhp. However in 1980, Honda went to town on the design of the CB125 'Super-Dream' expecting it to sell, significantly in Britain, as well as the former learner Legal CB250 Super-Dream, that accounted for about half of all 250 UK registrations.... they were dissapointed... 125 sales after 125 learner laws hardly increased over the few 125's they sold before!
However, we got a completely 'new' machine, that boasted a powerful twin-piston front t brake, over the twin-shocks cable operated russian-roulette-rotor, sophisticated mono-shock rear suspension, full regulated, battery damped 12v electrics with beefy generator for a 125 to give some belt and braces dependability to the e-start only engine.
DIFFERENCES?
Lots. It was completely re-engineered. The motor in the Super-Dream shares the major mechanicals of the earlier T-Shock bike, BUT.
Generator; went from 6v AC direct lighting and points ignition, to a 12v, all regulated, inductor trigger CDI ignition system.
Generator casing, and stator back plate was revised to house the new generator and the E-start mechanism. Crank-cases were revised to accomodate lugs to mount the starter motor. The primary drive casing was revised, to loose the kick-start mechanism.
Internally; not sure about the gear-ratios, though both have five speed gear-boxes. Most is the same I believe. Though head castings have different part numbers, though valves are the same part number, so likely that they are the same casting, and difference is a detail revision such as the finish, early motors being silver, later ones black,
Main components that were changed during de-tuning to UK 12.5bhp learner limit; Cam-Shaft, got significantly softer profile; the inlet manifolds are shorter, a different shape, and smaller internal diameter, and the carburettors are a different variant of Keihin, and 24mm instead of 26.
Next question, can you use T-Spec parts to 'de-restrict' a Super-Dream?
Answer is yes and no.
Cam drops straight in, IF you can find one. They are rare as rocking horse poop.
Carburettors? Well, the 26mm carbs used on the T would fit Super-Dream rubbers, but be restricted by the smaller manifolds.
Choke mechanism, on the T-Shock is also on the left hand carb and rod-linked between the two. The Super-Dream's cable choke wouldnt work, but more annoying, the shorter and angled 'in' manifolds would mean that the rigid choke link would not allow the carbs to be fitted without removing the linkage. So carburettors would have to be hybridised.
IF you decided to use T-Shock inlet manifolds? Well they point the carbs 'out' from the engine, unlike the Super-Dreams that point them 'in'.
Using them, then would put the carbs further back in teh cradle, and put the carb-mouths up against teh frame rails..... you would have some major clerance issues, and wouldn't easily be able to use the stock air-boxes or proprietry stub filters.
There WAS a 'Full-Power' variant of teh Super-Dream made for some markets that had the hotter cam, wider inlet manifolds and larger, later generation carbs. I think a couple found thier way to Ireland, and some more to Italy and Belgium. But BOG OFF rare, bits even rarer.
Its NOT an easy task to tackle, and hinges on getting hold of that Cam-Shaft, and there aren't many around.
