    Hi Mohamed, That is a cool looking bike you have there. I am not too familiar with the newer models as it's not something we get over here and I don't know what performance upgrades are available in your region. Definitely like to see more of what you do to the bike though! Welcome to the forum.

    RD and DT LC are the same block, but gear ratios differ. RD has a close ratio gearbox and DT has a wide ratio. Close ratio is not ideal if you want to go offroad IMO. Primary drive with clutch and 'middle shaft' length differs in the the LC engines I compared. Definitely get a LC YPVS engine if you go that route, -more usable power than without power valve. I have a DT LC YPVS close to stock, I reshaped the head and installed a Zeeltronic and put in 0,3mm carbon reed petals, the rest is stock. Goes well and has really good midrange torque for a 125. I think the DTR and TZR engines are the same block too, but there is probably the same gear ratio difference, and possibly more I have not tried dropping in a DTR engine in a LC frame (have only one DTR engine and many LC's), but have thought about it. Let us know if you try it!

    @Stevie-Wonder Thanks bud :+1: Greta (for that is her name as she's noisy, irritating, aimed squarely at the youth market and responsible for thousands of them bunking off school all over the world) cost me half as much as my '93 due to the mileage and had a thick layer of grime all over due to years of grinding commuting. I gave her a scrub with Jizer (several times) and this is what was underneath :flushed: Here are the part #s for the toolbox and lid, bit pricey IMO and you'd have to get the lugs welded on to a non-e start frame. Be a nice touch if you were getting it powdercoated sometime though https://www.cmsnl.com/products/boxtool_55v2817301/ https://www.cmsnl.com/products/lid_55v2818500/

    @theportingmaster I mean, it's 20 years old so I wouldn't be too worried if it's not concourse. Espcially if you want to use the bike daily etc.

    @HOTSHOT-III Thanks for the information mate.

    I have just bought a dt125r 1999 model. I'm mixing my own fuel. Can I put the same oil in my engine as I'm putting in my fuel tank?

    @brian-stephens True, the blue is also hard to reproduce, i got side panels reproduced a while back and red was ok but the blue stood out more. If your doing the whole bike you wouldn't notice it though

    On a stock bike it just doesent make much sense but on a modded bike it could be cool to have a non standard kickstarter to make the bike that bit more unique

    @stevie-wonder. I've tried yz 125 std and rfx they work but have slight play which will destroy the spline, I have to wear boots as it my woods n greenlaner and the std one is too short, everyone is saying 85 Levers. But the yz apico says for 85 125 250 everything so not realy sure what to buy yet

    @calum I actually love the guy man. I find his videos like a mechanic equivalent to watching Bob Ross 😂 I’d be curious to meet the chap in person he just seems so down to Earth and simple yet intelligent

    @rking7888 not sure tbh as they are different so no idea how close they are for this type of fit You could always make some yourself from some 3mm (or similar) aluminium sheet and attach to the rear brake MC bolts

    Yamaha TZR125 Yamaha (Belgarda) TZR125R Yamaha TDR125 (Deltabox) Yamaha DT125X/RE Yamaha DT230 Lanza Yamaha DT200WR Yamaha WR200 Yamaha (Belgarda) TDR125 & TDR125R KTM LC2 & Sting Derbi GPR125 2T Sachs XTC125 Sachs ZZ125 Best thing to do is use the Fowlers of Bristol website to get the Yamaha part number for anything that you need and then to put this into Ebay, Google, CMSNL to see if its still available. Always worth looking for new prices first and then looking at second hand if you have to as they can sometimes be "ok" new.
