If you want to get to work, carry a butty box and do it all on about 69p per day, then the Suzuki GS125ES is for you. It's about as exciting as cold porridge, but like the Honda C90, or Kawasaki KH125, the Suzuki GS125ES simply provides basic two wheeled transport and costs peanuts to run.

Basic suspension and skinny wheels, with later Suzuki GS125ES models featuring cast alloy items, offer a slightly bouncy but competent ride. Probably more rebound in the beefy dualseat than the Suzuki GS125ES's twin rear shocks to be honest...

The Suzuki GS125ES's four stroke single cylinder motor is virtually bulletproof, but makes a claimed 12bhp... eventually. A five speed gearbox lets what power there is get you to a cruising speed of about 55mph, although the Suzuki GS125ES will buzz its merry way to about 65mph on a good day.

Change the oil once a year, adjust the chain occasionally and put petrol in it. That's about all you'll need to do to a Suzuki GS125ES in a typical decade of ownership. The mid 1990s Suzuki GS125ESs had a black painted exhaust which tended to look tatty in winter, but otherwise a durable little bike.

If you can pick up a Suzuki GS125ES from a bloke called Derek, who has burbled to work on it for the last eight years, you will find you have a virtually indescructible commuter for as little as 500 quid secondhand. Bargain. Find a Suzuki GS125ES for sale.

Relatively roomy seat, tiny nose fairing and a digital gear indicator on later model Suzuki GS125ESs are the main highlights, on what is otherwise a basic, no-frills mode of transport. The Suzuki GS125ES does have a centrestand however, which some 125cc custom/commuters lack.

Very reliable and good little bike for getting around. Cheap to run and always good fun to ride, a great 125 for starting to ride with little cost.

Breaks are a bit sluggish but will stop... eventually. The suspension works great as well but can be a bit bouncy at times.

Engine 5 out of 5

After fixing the engine and carburettor and fine-tuning it slightly, it runs quicker than you can expect. Easily gets you to 60mph and after a while (with the wind behind you) can accelerate you to a whopping 75mph... No better feeling in the world than a 125 overtaking other cars on the dual carriageway.

Reliability & build quality 5 out of 5

Wasn't exactly love at first sight. It wasn't running optimally and started breaking down a lot as previous owners neglected the poor thing. After giving it a fix and some fine tuning, it runs with no problem now and will bring a smile to your face.

Value vs rivals 5 out of 5

Oil and cleaning is all it needs. You'll end up spending more on polish and T-cut.

Equipment 5 out of 5

Comes with a few neat features for a bike of that era but for the modern day, the headlight can be a bit dull, but still provides a very decent and bright light.

Best, lightweight, nippy, frugal. Worse, awkward gear lever, easily adjusted, keep on top of rust.

I bought mine of eBay for £500 I needed a cheap run around after selling my C.G and doing my D.A.S and decide to go for a G.S has you do not see many around, do not know why as I have found it a good little workhorse far better then a C.G with rev counter and kill switch and trip counter similar to a big bike, if you are thinking about getting then do it. I wish I had bought mine sooner and do not forget that all Chinese geared bikes are based on this engine why pay more instead get a geunine jap 125 that will last the course

Mine has disc on the front and drum on the rear with being a esm model which is the best of both worlds

The engine is ok on mine it is not fast but it is not meant to be fast, just for knocking about on

Reliability & build quality 5 out of 5

I went for a jap 125 rather than a Chinese one for build quality and cheap parts

Value vs rivals 5 out of 5

I change the oil and filter and few others jobs like chain adjustment I can do myself the petrol a week is £7.00 which is about 110miles give or take

It has two wheels, it goes forward, around corners, and pop the occasional wheelie. Oh and it never dies.

Ride quality & brakes 4 out of 5

I can ride all day long, in wet weather the front brake can bite a little hard and throw the back, but a little feather and the unlockable rear drum soon fix that.

Engine 5 out of 5

Bobba Bob Bob, pull pull pull, this little tinker can smash out a whole 12hp and a little more I suspect at above 9000rpm, red line at 10500.

Reliability & build quality 5 out of 5

5000 hard miles on top of 30000, and I've only had to replace a tyre.

Value vs rivals 5 out of 5

Add a tooth to the front sprocket, keep the tyres up, don't thrash it and get an easy 100mpg. Mine takes a drop of oil occasionally but at almost 20 years old it's to be expected.

Equipment 3 out of 5

My bike was not standard, no grab bars, lack of centre stand. However, electric start, manual choke, twin headlight and really bright 12v indicators will get you through.

Buying experience: Private purchase, bike was in a bit of a state, but did run, and at less than £320 no one could complain.

I decided (after 8years in a car) that rather than just jump to my big license to get the hang of 2 wheels on a little 125. This is how I ended up with my little GS125 and I have to say after a few months I have become rather attached to the little thing. It's been very reliable aside from a dodgy relay and a frayed throttle cable (both very cheap and easy to fix) Gear indicator is a nice little touch, rev counter is useful and having the center stand makes life soo much easier at times than just having a side stand Best way to describe it is a mountain bike with an engine. Very comfortable seat and riding position (even at 6'2"). The bike is so light it is very easy to just flick through the corners and the engine is quite happy to be thrashed (for progress keep it spinning above 5k rpm). Only downside is it tops out happily at 55mph, I have had it faster but you have to almost lie down on the bike and it isn't worth it for the extra 5 mph. I live in the sticks and getting round tractors takes some doing (but that could be aimed at any 125 I suppose). Like it enough I will be keeping it as a commuter when I pass my test (hopefully next year). It has certainly given me the 'biking bug.

This bike is very reliable, i bought it for £350 and have never had any problems. Starts first time in the mornings (hot or cold), Came off it once and it just slid along the floor - no damage done!. Really think you should buy one, very good to learn on. Bit bouncy but still handles very well. Great bike 10/10
