Overall Rating 4 out of 5

With incredibly low running costs, modest but useful urban performance and funky retro looks, the Suzuki GN125 is an ideal about-town motorcycle or learner bike. Incredibly easy to ride, with a reliable engine and minimal maintenance, the Suzuki GN125 is forgiving and a great confidence-builder. Lousy brakes and finish let it down a bit but, for a real world workhorse, the Suzuki GN125 is a bargain.

Ride Quality & Brakes 3 out of 5

The natural riding position means the Suzuki GN125’s comfortable, even over longer distances. Suspension is on the soft side but manages to deal with everyday roads but the brakes (especially the front) lack bite. Handling’s light and the ride’s confidence-inspiring and stable. The Suzuki GN125 can get vibey at higher revs, however.

Engine 4 out of 5

The Suzuki GN125 engine’s taken from the earlier GS125 machine which came out in 1984, so it’s safe to say it’s proved itself. A simple but reliable single, it’s nippy enough in town although runs out of breath on the open road and hills can present a problem if you’re in a hurry. The Suzuki GN125 can be stroppy when starting from cold. Needs plenty of revs.

Build Quality & Reliability 4 out of 5

The Suzuki GN125 is a tough little bike with a trusted engine and chassis. The finish isn’t marvellous: rust around welds and shoddy paintwork are common complaints. However, the Suzuki GN125's styling’s cute and nice touches include chrome indicator stalks and mirrors. A lack of cheap plastic gives the Suzuki GN125 some retro appeal.

Insurance, running costs & value 4 out of 5

A good, no-frills budget learner/commuter motorcycle. The best bargains can well be ex-training Suzuki GN125s where any damage is cosmetic but engines are sound. Parts are cheap, insurance is a giveaway and mind-boggling fuel consumption figures mean the Suzuki GN125’s ideal as an inexpensive runaround. Find a Suzuki GN125 for sale.

Equipment 4 out of 5

The Suzuki GN125's clocks are simple and, bizarrely, there’s a gear indicator but no fuel gauge... There’s also a long, comfy seat, with plenty of pillion space, and a grabrail. The mirrors are good but almost too wide: Suzuki GN125 owners complain of hitting cars whilst filtering! A few car drivers complain too... There’s also a small tool kit with the Suzuki GN125.

Wont start when cold but starts when pushed

21 January 2013 by madmadi

Hi guys, I need your help. Firstly my bike's details: Suzuki GN125, 2004 year, chinese version, 120,000 km done Carburettor Mikuni: http://www.brooksbarn.co.uk/GN125-CARB-NOT-H-MODEL-SILVER-TOP-DIAPHRAGM-TYPE_ART61.aspx Now the problem.... Read more Engine won't start from electric ignition when cold but it does start when pushed and it does start when engine is warm. New battery, new spark plug, fuel is going to carburettor freely (checked fuel tap filter), there is a good spark (taken spark plug out and touched to engine and pushed the ignition, good spark) So, there is a fuel going freely to carburettor and there is a spark. I have cleaned the carb, but to be honest there was no rubbish in it. There was some white stuff in the rubber hose which is going from air filter to carb, like soapy stuff. Adjusted a fuel/air mixture as was told by friend that maybe there is too much fuel and not enough air- when cold and rainy outside (live in Scotland) maybe the air filter is getting wet and there is not enough air going to carb? When trying to start the engine there is an explosion sometimes. Trying to start it with and without choke which is manual of course. Another thing, the fact is that the engine starts sometimes even when cold, I just observed that there is a problem when is wet outside (keeping the bike outside) The problem started recently, but as I said it sometimes starts, sometimes not. I use the bike everyday for going to work which is 8 miles one way. After 8 hours of work it starts most of the time, but after night it doesn't. Almost always it starts when pushed and from the 2nd gear. By the way, I don't know if that's normal but when I start the engine on the choke and it starts the revs are around 4000rpm but sometimes after 30secs, sometimes after 2 minutes revs going down to 1000rpm-1500rpm - does it mean that engine adjusting the choke automatically when warm? Doesn't it suppose to have big revs when choke is fully open, even when engine is warm? Now few possible reasons (in my opinion): Wrong fuel/air mixture (even after adjusting it- half rotation on the mixture screw) Bad compression Wrong valve settings (gaps) Ignition settings Blocked fuel stream from carb to engine (?) Choke problems Any ideas??? please email to madmadig @ gmail.com Thanks in advance, Martin

Good on a budget

15 September 2011 by TH427

I bought a 2000 reg 17000 mile for £475. It was pretty corroded but I tidied it up a bit. Hammerite and high temp spray paint can do wonders. When they say stroppy from cold it really is. Will start in even the coldest of temperatures on choke but... Read more then won't tick over til warm. I found starting it then riding it down the road and just having to hold the throttle open when in neutral or stopped etc til it's warm is better than just sitting there revving it til it's warm to set off. The engine is quick enough around town, but anything over 45 is painfully slow progress, the engine vibes make you think you're ragging it more than you are. I saw 70mph down a hill with a tailwind and my chin on the clocks. Top speed of 60/65 is realistic. Compared to the CG125 and YBR125 it is a bit slower. Neutral can be a bugger. Fuel economy, 100mpg all day long. One thing I never noticed before getting my 600, is how bicycle light it is. Suspenion is bouncy but fine for a budget 125. All day long comfy. Finish is good enough. Servicing can be done by a ham fisted ape. The front brake is good enough for a 124 (just), but the rear drum is awful, totally lacking in feel. But despite all these things I found it easier to ride than the CG125 I did my test on and the YBR125 I did my CBT on. It's the aslmost the perfect learner bike. Cheap, economical, nice looking, crashes well (whoops) and will sell on easily when you've moved on to bigger and better things.

ive had my 06 gn for nearly 6 months and i love it, according to the clocks it does 85 but i think its probably just over 70. i hate hills and its bugs the hell out of me not being able to overtake. i was worried when i found out it didnt have a fuel... Read more guage but only a monkey would let a bike that uses so little fuel run dry. i love the bike to bits, i just wish it went a bit faster. it starts first time and is realy reliable, ive only come off once on black ice and it cost peanuts to repair.

As First Motorcycle

18 February 2008 by speedsis

Good reliable motorcycle as a first bike for a learner. But sadly lacking in the speed department I got my up to 53 mph once when going downhill but usually it was 45 - 48mph and at 50mph you could hear the engine struggle and had to quick shift... Read more down. Using the bypass was a bit dangerous as well because the traffice moves so quickly and cars tend to cut you up if they can, I used to stay firmly in the middle of the lane to combat the bully car tactics, you do need nerves of steel for this, but then when a good car driver came along I didn’t mind moving over to let them pass. Going up hills was a big problem, we have quite a few in Lincolnshire & my favourite riding place is the wolds. Overall it was a good reliable motorcycle. (If you don’t have hills to contend with).
