MCN overall verdict rating is 4

Derbi’s Terra Adventure 125 is a fantastic looking machine which bears more than a passing resemblance to the best selling BMW GS – albeit in a learner legal package. If you’re looking for adventure on a budget or just a small capacity bike to have some fun on you won’t be disappointed. 

Engine

MCN rating rating is 4
Owners' rating rating is 4

Derbi’s Terra Adventure 125 has a four-stroke, liquid-cooled engine that kicks out a claimed 15hp and should be good for a little over 70mph. The Derbi Terra Adventure 125 may not have loads of power but it loves a handful of throttle and will happily rev to 11,500rpm.  

Ride and Handling

MCN rating rating is 4
Owners' rating rating is 4

The Derbi Terra Adventure 125 showed its pedigree out in the wilds and handled the terrain perfectly. Great suspension front and rear, fantastic brakes (which stayed sharp despite our heavy abuse) and precise steering all added up to one of the best learner legal rides around. The saddle sits at 815mm but due to its narrow profile actually feels much lower, so riders of less than average height can manage the stylish 121kg bike.

Equipment

MCN rating rating is 4
Owners' rating rating is 3.5

The Derbi Terra Adventure 125’s styling is well thought out, perfectly executed and also has a bash plate to protect that vulnerable engine whilst you’re living the dream out in the countryside. So, not only does the Derbi do the job, on or off road but it also looks the part and gives the appearance of a larger capacity bike. Compare and buy parts for the Terra 125 in the MCN Shop.

Quality and Reliability

MCN rating rating is 4
Owners' rating rating is 4

Derbis have long been classier and better quality than most 125s – think Aprilia and you won’t be far wrong – and the Terra Adventure 125 is no different than most. Finish is generally good and, thanks largely to the Minerelli engine, there are noi reported reliability problems yet, either.

At around £3K, the Derbi Terra Adventure 125 is in the high-end category of learner bikes, but for the most part you get what you pay for. Besides, compared to other, bigger dual purpose bikes is that you don’t need a mortgage to own one. Find a Derbi Terra 125 for sale.

    I bought my Adventure model back in June as something that I could learn on with a view to riding a large sized 125. I get an average of 75mpg mostly duel carriageway miles and using 97ron fuel which the engine really makes the best use of. The bike is well made, and easy to keep in good order too which is good. The headlight is good, and the brakes are as good as anything else i've ridden thus far. The under-seat storage is pretty much nil, only enough room for a phone. I had to really hank up the rear shock to make it handle as it felt a bit floppy before on some bends. The screen is great - it keeps off a good deal of wind and rain on bad days, and the handlebar wind guards are really useful!! It certainly gets a good amount of attention - isn't the usual 'pizza delivery' bike and will go off road, though the first gear is a bit high for the big hills at crawl speeds!

    Had this Terra for 4 months now, use it to go to dialysis three times a week, 20miles round trip on A roads. For a 125 it is "spunky", quick off the line and the handling is top notch. But to me, it is not made for the weather we have over here, I got mine in Dec and even after covering it in ACF50, most of the metal work has corroded or rusted, side stand sensor has gone pop, fuel reserve sensor will say your on reserve if you go over 60 and I have had an almighty scare when the electrics -lights, dash etc, went off one night, then rebooted like a pc, not nice when approaching a bend in the dark. This bike could have been the best 125 on the market, even though it is fun to ride and sort of economical, getting 75mpg....but I am throttle happy, which this bike needs.

    As a seasoned owner of large capacity machines over a 30 year period, The Terra 125 has come as a revelation. Purchased originally for my son to learn on, it is now my Sunday 'bike of choice' for cross country rides involving A, B, C graded roads& righst of way. Well built, plenty of power for a 125, light, tall & accommodating & very flickable in all conditions. There are very few roads on which this will feel out of its depth. You could spend 5 times the money on 10 times the capacity for an adventure bike but you may not have as much fun. Definitely recommended

    This is a nice capable machine,and easy enough to live with.Engine is willing but needs to be revved,gear changes need to be done between 5 to 7k revs.It is quite economical although i have not done any long journey's on it yet so no figures yet.The seat can be a pain to replace once removed,there seems to be a knack to it however.One thing that needs to kept an eye on is what i beleive is the water trap underneath the airbox (looks like an elongated teet),it needs to be emptied regularly or will fill up and the contents seem to be sucked in by the carb which will cause difficulty in starting.

will it last...

Just to give an update of my experience; after only a short time, I noticed the exhaust had rusted on the tip... The black coating had flaked away to reveal rust, having contacted my dealer they were happy to order a new replacement exhaust under warranty.

The bike has had it's first service, although I was not too happy with the person in the workshop who over-tightened the clutch lever as I was getting used to the light control; now the biting point is much further up.

Sadly, the bike has developed a fault in that; the red oil pressure warning light is now on canstantly, the oil level is fine so it's back to swindon for another look-see.

Although I do like the bike, I have also noticed a brown/rusty coloured liquid coming out of the frame, located at the bas just by the kick-stand... There are two small holes in the fram, and this is where it's coming from.

Now, if the bike is rusting from the inside out then I would definately be wary of these machines in the future, it's only a 2011 model and has not seen any off-road antics, so I may have to try for a replacent bike of the same value and not another Terra.

The bike corners very well and can easily hit 75mph, although of course, you will have to rev it up there!

i also bought a top-box and can attest to the fact that; strong wind does not make for the most comfotable of experiences, it's much better without the box fitted, I found the commute to work fine, but any 'fun' rides I will be leaving the box at home.

So, the long-term quality of the bike is not looking good, I am not sure that it will last.

I'll keep you posted of the relutls this thursday.

Derby Terra 125

I have recently bought the non-adventure model...

As the poster above me, I also find the seat a little fiddly, thanks to the advice above I have kept an eye on the 'teet' also and have had to empty it once.

I am now getting used to the bike, although I have only done 300 miles on it, mostly A,B and town roads, my brakes were tack sharp from new, however, since making the schoolboy error of getting carried away with the ACF-50, the brakes have become a little spongy. Thats nothing to do with the bike, rather my own mistake.

I feel the bike handles really well and have not had much issue with wind buffer at higher speeds, although I have to say, with nearly a full tank I have found the ol' U-turn to be an issue and usually find it difficult to get the bike round a lot of the time, you definately feel the weight when you missjudge the angle...

I also find myself regularly slipping into neutral unexpectedly on occassion, although I'm sure these issues are down to my inexperience.

Overall, I find the build quality to be quite good, from other bikes that I have looked at, they all seem to have wires showing here and there and as with the teraa, are not all neatly hidden away under rubber sheathing.

I also find the rear brake lever to be a bit on the insubstantial side, it feels too short and with no pad/peddle your foot can feel uncomfortable after a couple of hours riding, also the clutch lever seems to be a bit loose, this may be normal of course and just part of the braking in... these things, I assume naturally loosen over time?

The body work seems nicely finished, paint wise, although the stuck on name graphics feel a bit rough and can be caught with clothing etc and 'rough-up'. The suspension seems perfect, for me, although you are going to feel the odd pot hole here and there, the tyres grip nicely and as yet, have not skidded or felt like I was going to, the only bug bear with the wheels are; the disc brakes will rust up on the inside of the cut-outs, these holes seem to not have been treated/coated... this is where the ACF-50 became an issue with the brake pads, even though I thought I was careful (using cotton buds to apply). Also, I would have prefered alloy wheels instead of spokes, mainly because I'm from the camp of; less cleaning/anti-corroding, the better.

The radiator seems to have picked up a hole here and there, I count three... all the same size and I assume from stones on the faster roads, the zig-zag grill is very fine/thin/fragile so again, nature of the beast I guess..

The throttle feels nice and loose, and I find the riding position very comfortable, yes the seat is fiddly and could provide a tighter, more flush fit, but it is comfey.

Finally, I have never been able to get the bike to start without any throttle, a friend tells me this is quite normal, despite my expectations/missunderstanding of an electric start motor.

I would recommend this bike and agree with the main review when they commented on the seat height, I can get both feet on the ground with a 30" inside leg.
