Yamaha RD125LCIn 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.

RD125 LC

Yamaha RD125 LC Mk2

Yamaha RD125 LC Mk2In 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

Yamaha RD125LC Mk3Yamahas 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

RD125LC Mk3The 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 to death.

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.
