Overall Rating 4 out of 5

KTM has built a race replica 125 to meet Yamaha's YZF-R1 and Aprilia's RS4 125 head-on. This is a propersized bike with a spacious, sporty riding position and plenty of room even for a six-foot big un.' 

Ride Quality & Brakes 4 out of 5

The RC’s steering bears all the right sportsbike hallmarks – light, flickable and capable of lightning direction changes. On the road it’s just brilliant, bowling along with the motor in its sweet spot, dancing on the gear lever, holding off the excellent brakes for as long as possible. The limiting factor when pushed hard, surprisingly, isn’t the tyres - it's the suspension. The RC’s WP forks and shock feel budget and can, under hard cornering, lose control and start chattering mid-corner. You’d think being WP – who are owned by KTM – it would be better.

Engine 4 out of 5

Limited to 15bhp, it’s easy to assume the RC’s engine will be similar to other 125s – and, at first feel, it is. The throttle is effectively an on/off switch, and the motor needs a big smearing of clutch to get away at the lights, just like a two-stroke. But the gearbox is smooth and clutch action light, so it’s easy to blend drive into one long slur of acceleration. And once rolling, the engine doesn’t feel artificially restricted; it gathers momentum smoothly and with as much gusto as the law permits. There’s nothing of substance below 8000rpm and by 10,500rpm it’s all over, but 2500rpm is just wide enough to hold 60mph at a vibe-free 8000rpm. Top speed is an indicated 84mph.

Build Quality & Reliability 4 out of 5

Designed in Austria and built in India, the RC125 features WP suspension and Bybre brakes (Brembo's Indian division).

Insurance, running costs & value 4 out of 5

Big-bike looks, great steering, sweet engine, good brakes and clever features at a premium price put the RC at the top of the 125 tree. But it loses a few points for cheesy details and feeble suspension. The KTM's price is just above rivals - which is fine, as long as build quality issues don't emerge.

Equipment 4 out of 5

Superficially the RC125 looks the part. Its sharp, angular fairing, tank and seat unit maintain a KTM family resemblance, and under the skin there are good ideas as well some obvious budgetary constraints. Clocks are well spec’d with fuel gauge, gear position indicator and various trip functions. Pillion pegs are nicely sculpted and the tail unit is made from soft rubber which looks like a solo seat but is actually a pillion pad.

Brought this to start getting into bikes again and it has done its job. With it being so light weight able to throw is around corners with great control. Being a 125 speed was something knew it would lack but makes up for it in acceleration and... Read more comfort.

Ride Quality & Brakes
4 out of 5
Ride quality is good as your not to hung other the tank all the tine. Helps save your back for a few more years. Brakes are good rear one is almost to responsive and has almost cost me to lose the rear end a couple of times. Being a slightly heavier guy 85kg has meant the rear shocks go down a bit. This brings up the front causing the light to shine into cars. Not an issue for me but people do seem to get a bit annoyed about it .

As I said earlier the engine is good a reliable. You know your know going to be going fast on a 125 but can get 86mph. Acceleration is good and helps you to pull out winding corners.

Had an issue early on with the bike where the high beem rely set on fire. Not what you want to see under a fuel tank. Luckily warranty covered it if not would have been cheap to replace. The rest of the bike is solid. No other issues and you have the ability to upgrade the majority of the bike.
Value & Running Costs
4 out of 5
Cost 8 pound Max to fill up which is nothing. Last 170 miles is depending on the riding your doing. Services are priced just as any others are so you should know what to expect .
5 out of 5
The equipment is amazing with the standard ktm speedo allowing you to see everything. The only annoying thing about it is the flashing red light (which indicates to change gears) is set to low . However this can be altered to suit your riding style. All finger controls aren't put of reach so easy to indicate, full beam, flash and beep.
Buying experience

Brought from a dealer which I do recommend as it gives you the safety with warranty should anything happen. They didn't try and upsell much but can by cheaper alternative which are just as good online.
