MCN overall verdict rating is 4

At £3999 OTR there are cheaper 125s but then none of those rivals have the same heritage or kudos. Despite making only 15bhp it’s great fun to ride - the fact the new four-stroke engine thrives on revs keeps the old RS spirit alive. It handles well, stops well, and most importantly looks the part. What more could a 17-year-old want?

Engine

Pulling away requires a good twist of the wrist to get the new four-valve, four-stroke engine spinning and keep up the momentum. Compared to some 125s the RS4 needs to be revved and ideally kept above 8000rpm. Even som the Aprilia accelerates briskly upto 40mph before starting to level off.

Ride and Handling

MCN rating rating is 4
Owners' rating rating is 4

Due to the light weight the RS4 handles brilliantly. Flicking it from right to left is a doddle and should you need to change your line during a corner, a slight push on either bar will suffice. The launch bikes were shod with super-sticky Pirelli SC1s which really showed off the full handling potential of the RS4. It's surprisingly roomy and, compared to the old RS125, feels slightly less sporty which is a big plus.

Equipment

MCN rating rating is 3
Owners' rating rating is 4

Radial brakes, braced swingarm, max speed function and braided hoses are all standard on the RS4 125. One of the accessories which will beavailable is a quickshifter. It only really works weel if changing up right before the rev limiter at 11,000rpm, changing anywhere else results in a very clunky and crude sounding gear change. But a quickshifter will give you major bragging rights over your mates.

Quality and Reliability

MCN rating rating is 4
Owners' rating rating is 4

The new four-stroke 125cc engine should be much more reliable than the highly-strung two-stroke engine of the onld RS - which was often neglected by teenagers. The bikes never missed a beat being held at full throttle virtually all day in 30°C plus heat.

Value

MCN rating rating is 4
Owners' rating rating is 3

£3999 on the road sounds like a lot for a 15bhp bike, but when you consider the Yamaha YZFR-125, arguably its closest rival, costs £4,249 it doesn't seem so bad. Yes, there are cheaper 125s out there, but none of them are as cool as the Aprilia.

    I have both the 2 stroke and 4 stroke rs 125's, the 2stroke version is faster and a lot more fun to ride but the new rs4 is still a good bike, handles well, quite nippy {Quick shifter helps a bit} Only rode the bike for 50 miles so not had a chance to give it a good ragging yet but will do after the run in-period

Comfortable at speed?

Any ideas what speed this bike will happily cruise at (in 6th) for prolonged periods? Thanks...
