WHAT TO LOOK FOR
1 Rear suspension
Monoshock was soft from new and you, frankly, aren’t as light as you were at 17. Budget for a decent aftermarket replacement.
2 Rear linkage
Aluminium rocker lends competition kudos but do check that it has been regularly lubricated. Kind of unlikely, if we’re honest.
3 Expansion chamber
If it’s been cut to remove restriction it might not have been rewelded or refinished neatly. Take a close look at the barrel end and the beginning of the expansion chamber.
The RG125F was equipped with an electric start only. This and other electrics may suffer the usual age issues.
Pressed steel so look out for corrosion and crash damage which can be costly to rectify.
Not the smoothest shifter but rapid enough. Don’t worry if it feels a little notchy.
Suzuki made much noise about the SBC plated bore. It wasn’t that good. Budget for a replate if it hasn’t recently been redone.
Some had a tendency to break, wreaking merry hell in the barrel and head. Poor maintenance and a loose bolt were the usual culprits.
If you’re looking for pristine you’ll probably have to stand back a little and squint a lot. If it’s all there it’s a bonus regardless of condition.
10 Front brake
Floating disc and four-pot Tokico prompted much bragging in their day. They’ll still see you right now on the lightweight RG-F.
