Produced by Brighton-based Sinnis, but manufactured in China, the Trackstar is a cheap, trendy 125cc alternative to the CG 125 or the Virago. It’s very easy to control and manoeuvre, making it an attractive option for learners or novice bikers. It’s also got the looks and charm to interest scooter riders, commuters or city-dwellers who are won over by its unassuming, low-power appeal. Price is the biggest selling point, at £1,549 new it’s unparalleled, and if sales take off Sinnis may just redefine our perception of Chinese-made bikes.

The brakes are gentle but effective, after all at 107kg there’s really not much weight to stop. The riding position doesn’t put any stress on your back or legs and the bars are half-way between street bike and cruiser. It’s easy to lean around corners, has a fantastically small turning circle and the springy suspension is aimed more at comfort than performance. It’s very, very light and manageable, making it good for the commuter, the rookie and the petite alike.

The single-cylinder, air-cooled, 4-stroke 124cc heart is based on Suzuki’s GS 125 engine. Sinnis use more or less the same design across their range and it seems to do the job perfectly well. Vibration becomes quite off-putting and uncomfortable at the top end of the rev-range, but cruising at 55mph is perfectly smooth in fifth gear. This is still an 11bhp bike, so power and torque are not things you’ll even consider while riding it. That said, once you’ve fought your way up to cruising speed it’ll hold it well and makes for a relaxing, un-threatening experience.

Quality is good for a budget bike, though it is obviously built for affordability, not luxury. Sinnis offer a two-year warranty with all new models, which offers peace of mind and shows that they’re confident in their product. To keep the warranty valid they ask that you have one service at 635 miles and another at 2000 miles. There haven’t been any reported problems with the other models in their range and they claim they’ve never had a case of engine failure.

At £1,549 the Trackstar is superb value. That’s £450 cheaper than a CG 125 for a very similar product. By trying to prove to the world that Chinese built bikes can be as reliable and attractive as their Japanese or European rivals, Sinnis have given themselves a difficult job. However, with such aggressive pricing, and a bargain little product, they might just be on the verge of doing it single-handed. Find a Sinnis for sale

The retro styling is cute and appealing, with a pleasing little speedo, digital gear indicator and comfy stitched seat. The mirrors are large and well placed and the electric start is welcome. The best word to describe the bike is ‘dinky’. It can’t carry much weight, but it’s frugal, good looking and has the same kind of dainty charm as a miniature railway. That said, what you see is what you get and there are few features beyond what’s legally required. Compare and buy parts for the Trackstar in the MCN Shop.

Sinnis’ Stealth, Apache, Blade and Vista all use the same engine as the Trackstar, it’s the frames and stylings that are different. Worth investigating if all of the above sounds tempting.

As far as Chinese bikes go this is my favourite. The sitting position is perfect, it's not too high so less crosswind issues compared to my mates. Best features are the looks of it, it draws you in with its retro style. The worst thing is the electrics, this is almost a 5 star bike but I had continuous issues with headlight bulbs blowing and then one bulb arched the high beam to the low beam and burnt my electric out, I purchased a brand new headlight, Speedo and rewired half the bike but sadly it's still off the road right now. The electrics with vibration from the bike at top end really let's it down.

Ride quality & brakes 4 out of 5

Brakes are adequate for the bike, rear a little spongy but it's drum that's how they are. Ride quality is great to 60mph but then vibration becomes apparent and overall control feels reduced.

Engine 5 out of 5

This little Suzuki GN derived engine is spot on. Reliable to no end. Will happily sit 65mph and will slowly climb to 70 where it still doesn't feel as if it's struggling or maxed out but you know it's got nothing left to give. The final drive is set wrong though, 60mph in 3rd and 70 in 4th 5th gear really done nothing at all but 2 teeth smaller on the front sprocket levelled out the performance.

Reliability & build quality 4 out of 5

Never broken down, the engine is reliable, handlebars really corroded bad as did the chrome on the rear suspension arms and swingarm but it was never covered up and sat in a garden for 4 years so done better than many bikes would.

Value vs rivals 5 out of 5

Servicing is so cheap and simple, it takes less than 1ltr of oil in the K157 FMI engine, I go for £13 castrol performance but you can pick up a ltr for as little as £5. Oil filter is cheap as with air filter, spark plug is a few quid. Never cost me more than £25 for annual service. Seems like it drinks fuel faster than most 125's.

Equipment 3 out of 5

There really isn't any equipment further than what is legally required. It may be a simple thing but the fuel tap is my favourite feature. Changing the rear tyre to a Michelin City Pro has improved overall experience on the road especially in corners.

Buying experience: Bought privately it was advertised at £550 with 12 months MOT. I ended up purchasing it for £220. Worth every penny.

5 out of 5 Sinnis scrambler 125cc review
09 August 2016 by Dougie

Version: Scrambler 125cc

Year: 2015

For a relatively cheap 125 bike you can't complain. Good aesthetics and reliability.

Ride quality & brakes 5 out of 5

Never had any issues. The brakes are firm, the gears smooth and the seat nice and comfy. The upright riding position is ideal for commuting as well, not hunched over yourself like you would be on a sports bike.

Engine 5 out of 5

No complaints really. A Suzuki derived engine which has never given me any trouble. Has some good pull on it on the low end but as you get to higher speeds you'll find it takes a little while to climb up to the golden 70mph but it doesn't feel like it's overly struggling at those speeds too.

Reliability & build quality 4 out of 5

Never broken down and as long as you keep it clean it won't rust or corrode. Bolts on the exhaust guard snapped meaning the exhaust has to be replaced.

Equipment 5 out of 5

By far my favourite stock feature is the high riding exhaust. It was the exhaust which drew me to the bike originally and it's what continues to impress me today. It's gorgeous and really makes the bike in my opinion. Also stock it sounds great and rough, guaranteed to turn a few heads round the town centre.

Buying experience: Yes great and Sinnis' two year warrantee definitely holds up as they replaced my exhaust ASAP when the bolts on the guard failed. Sinnis also seem very active to their community and actually listen to their riders, enjoying the feed back. You get the impression the guys who work there aren't just there for the job, they're there because they love bikes and want to spread that love!

Great looking, light weight bike. I passed my test recently and can barely bring myself to part exchange the thing; it's such an agile bike, bang on for low speed city commuting. Stylish for a learner; and one to keep after test, for tinkering and backup riding.

Ride quality & brakes 3 out of 5

Most fun going slow and nimble. Terrifying at speed.

Engine 3 out of 5

It goes. Real power band in 3rd gear, taking bike from 20-40mph or so. Slow acceleration everywhere else.

Reliability & build quality 3 out of 5

Everything works, but stock consumables have me raising an eyebrow. Little corrosion showing in places where paint has chipped after 4 months. Cheap spark plug, cheap squeaky break pads front and rear... What else is equivalent low quality? Product manual poor. At least everything is accessible and easily replaceable. Tin of Hammerite will sort corrosion; it's so cheap I almost don't mind!

Value vs rivals 5 out of 5

Services demand low mileage - cost £180+ during 1st year to keep warranty alive - there's cost recouped here by Sinnis on the low purchase value.

Equipment 3 out of 5

Bars for bungee-ing a canvas tool roll, to fully look the part.

Buying experience: Sinnis main dealership. I want to like these guys, but they make it so hard... Paid £1595 OTR.

Great quality bike for the price. Uses the same bulletproof engine as the Suzuki GZ125 Marauder. Very light and with a low seat height. Perfect for learning or commuting. I dropped mine off its stand and broke the clutch lever, a mirror and an indicator. I rang my local Sinnis dealer and got them the next day. Great service. I wouldn't hesitate to buy another Sinnis bike.
