Light, good-looking in an early-’90s throwback fashion and, importantly, easy to derestrict. This is as good as 125s get
Suzuki RG125F and why it’s one of the best 125s you can currently lay your hands on
In the teenage world racing style, and to an extent pedigree, have long been key selling points. Never mind that The Man strangled your ride to a paltry 12bhp; as every 17-year-old worth their provisional licence knew, a derestricted 125 had plenty of unleashed potential once you’d, er, passed your test.
Suzuki’s RG125F, introduced in 1992, was touted as essentially one quarter of Schwantz’s GP racer powering a slippery-faired Gp-style bike. Never mind that in restricted form it had not only a quarter of the capacity but also a fraction of the power. Sure the 125cc twostroke single came with an AETC (Automatic Exhaust Timing Control) powervalve and a slippery SBC (Suzuki Boron Composite) plated bore.the former was disabled on the restricted bike and the latter redundant in hobbled form.there was also a forged aluminium piston and steel conrod.a balancer shaft aimed to ensure that all the vibrations would be good.
Other racy appointments included a Mikuni oval slide carb and a floating front disc gripped by a four-pottokico.then there were the upside-down forks.
So far so GP paddock, although a pressed-steel frame and crescent
swingarm had the right silhouette although the wrong material in steel. However a 125kg dry weight was the right side of light enough.
Keep the restricted bike between an indicated 8k and 10k and progress would be linear enough and along with fine handling would conspire to satisfy the nascent sportsbike rider.the fairing did a brilliant job for those not-so overgrown that they couldn’t tuck in behind it. Certainly the RG felt faster than its restricted status might suggest. Clip the wire to the ECU that prevented the powervalve coming into play and there was more fun to be had from the FN. Cut and shut the exhaust to remove the restrictions in there and it was doubled.
There was also a naked version, the RG125UWOLF with a conventional swingarm and right-way-up forks.
This was a golden era for the 125cc race rep for those heeled well enough to afford the Suzuki’s £3k price tag or those of, say, a Cagiva Mito or an Aprilia Futura.
Today prices for decent examples are holding firm, with interest growing among those who owned them back then as well as learners realising these old strokers have far more to offer than anything the manufacturers build today.
