the summer of 1982 the RD 125LC was unleashed
on the UK learner market. It was the successor
to the Air coold RD125 twin. They put a sporty
bikini faring and bellypan on it as standard.
Even though this 125 was restricted to 12 bhp
and 75 mph with a micron or allspeed (the pipes
of choice at that time) it could see just over
100mph on the clock down a good hill. With a
cantilever mono-shock swining arm italic style
wheels It addopted from its big brother the
250lc and a single cylinder water coold engine
it realy did look the biz. They just flew out
the dealers shops.

Yamaha RD125 LC Mk2
1985 yam updated the 125LC with the MK2. Theys
had rounded clocks replacing the dated rectangular
ones of the MK1. It had better thiker forks,
clipons with bare ends. Gone where the famous
itilic wheels swoped for straight spokes, puting
16 inch front wheel on it with and a braced
front mud guard and a diferent disk and an aposed
piston brake caliper, this improved the stability
and handeling and braking. The wheels looking
very simuler to the 350YPVS now on the market.
At this time there were quite a few 125's chomping
at the lc crown the RG, NS, MBX, MTX , KMX,
AR and yams own DT all sharing the sales.
Yamaha RD125 LC Mk3
next model the RDZ125 MK3 was unvaled in 1987.
This model was under a lot of compertishon from
the aformentioned bikes and was basacaly just
a stop gap while the TZR125 was being finished
of. The emphasis was on the motor with no real
changes to the bike its self. It was fitted
with a YPVS engine simuler to the one being
used on yams DTR125. It had a very nice looking
exhourst resembeling the F2 350 YPVS pipe and
the pipe fited to the still to come TZR125.
The powervalve was blanked of for the UK lerner
market, but you could get a powervalve kit to
get it runing, if you did boy did they fly.
I sell loads of theys kits for MK3 125's and
TZR's you get all the bottom end with all the
top end to as the valve opens up and you get
the full BHP to the back wheel. In Europ this
model was known as the Mk2 LC2 not the Mk3 There
bikes had a working YPVS
RD was replaced with the TZR 125 in 1987 witch
used the MK3 forks wheels clipons clocks and
caliper. The MK3 did not sell as well as the
MK1 and MK2 due to the other bikes allso avalible
at that time ( its hard at the top.) The MK3
is the rarest of all the RD 125LC's.
In there hay day there where loads of mods
and trick bits avalible for the 125lc. You could
get a full faring there where 2 types a TZ stile
one and the more popular TZR125 type as seen
on my MK1 in the gallery. You could get a 170cc
big bore kit, theys gave a load more power but
unfortunatley people did'nt bother modifying
the heads and often used the standard head gasket
and they blew up a lot . Young 17 year olds
just wanted to bolt on and thrash, and thrash
we did all day and all night. This was half
the problem with them they where all thrashed
Most of them even back in the day had several
owners people kept them for 6 months a year
and sold them. many of them have owners in the
20's and 30's . Finding a good one is hard now
is geting hard, and if you do come across a
retored 125lc you will pay as much for it as
a 350lc. A real nice restored one will fetch
around £1000, and a resonable one will
fetch £600, Witch as it hapend is what
i payed for my mint as new MK2 back in 1986
when i was 17.
Parts are hard to find for them theys days
and good parts are even harder. What do you
think the hardest part is to find is for any
of the lc's 125's 350's or YPVS's ? its a 125
lc knose cone, becourse all us lads took them
of and put them in the garage and sold the bike
then found the knose cone years later and threw
it and thows that wher kept on got smashed when
the bikes got droped and they all got droped
so they ended up in the bin.
