DT125R FORUM

Took the bike on my first little outing to the Forest of Dead yesterday to the Cotswold Biker Nite. Saw this GAWGEOUS Honda NS400R [image: sRgeDay.jpeg] Didn't know these were even a thing and it was utterly stunning in the flesh. Was extremely quiet as it set off down the road.

@HOTSHOT-III Glad to hear it, your help is invaluable.

Merry Christmas and a happy new year,wish you good health to all, everything else is obtainable.

Finally! Actually found some time to go out on this thing! [image: L5TZajj.jpeg] The original gearing I bought for this was a no-go and I ended up chucking it in the bin. Instead, I found a Trail Tech crankset made for an E-bike, had to swap out the bottom bracket, but the result is something which gives me the ability to go up a few teeth on the front (currently rocking 24t), blitzes up moderate inclines, but lacks real top end. [image: faXVi2L.jpeg] I managed my usual route easier than the 26er, both up and down hill. It just felt like it handled the rocky sections better than the 26er, the lower gearing made it easier to climb some of the hills I had to get off and push, overall I'm very pleased about how this one has turned out, hopefully get a lot of use out of this over the coming years.

Okay...so some overnight parts from Japan and CMSNL and some others from Australia I've finished the gearbox rebuild.....

This completes the output shaft rebuild.

[image: AP1GczPryZOZov8DT0-4jUeYt9z_7olcQbjIl_LvQWZucNyTLVWDzE4tiNqYCMewakgXjpUJA4aooJ7ag_6TJJfxkDdR1-7N3matX1AMPOzOpKTtpnvtfxdLqPCUuaQd6eWEpiiW5gXy_nO4xrbnAsFLSqab=w701-h1311-s-no?authuser=0] Fingers cross that's all back together correctly, I'll have to remember to select all gears and test BEFORE firing up the motor, else this will be £8000 down the drain if it destroys the motor.

[image: AP1GczNkYj3ORIWqQl0xC4kYfaZyJ1ywJV2dfvlihCnch34e7OrCJ1hJIc1Oh9EXyTvIBN8FWkZxZgKaWRp0BakEPsrsPAWWkLHEcPGATSnyyucBAsdvVx3W-xukLygatC3vIlJjx5vrvCrE_pRhpFoyG6KT=w1922-h928-s-no?authuser=0] Should go without saying, all near bearings and a lovely carbon fibre chain guard which I bought about 5 years ago for the Raptor. I'll probably keep the Raptor bone stock and therefore it's not needed for that project and can go onto this beasty. I did have some swinging arm spool spacers machined up but for the life of me I simply cannot find what I done with them. No doubt they'll turn up eventually.

Happy new year to all,I wish you only good health, everything else can be gained more or less. @Calum Thank you for the existence of the forum.

YAY! What has been, three long years and the bike is finally on its own two wheels again. [image: ILujNIK.jpeg] Trip down to the powdercoaters to pick up the suspension spring as it just didn't feel right to put the crusty one on there. [image: 2aP5114.jpeg] I had it repainted the OEM colour for this bike, but fitted the RX/MX/SX shock absorber. It was refurbished to the best of my abilities. [image: 2QH7PxV.jpeg] Sadly the bike isn't concourse and never will be. [image: 1CoLTaZ.jpeg] But it's starting to come together nicely now! [image: 7k2txzW.jpeg] And at least I can move it around the garage out the way of the other bikes finally! [image: V9jlvnt.jpeg]

@Calum What an excellent use of space, and a first rate job!! Steel section on the bench and a pillar drill somewhere will finish it off nicely.

@Rxvert2k-0 Hello Yes lots more updates. I've taken photos, but I am awaiting a good point at which to update this thread. I've bought: A bunch of Aprilia RX125 parts (better spec than ETX) Aluminium Swinging Arm Gas Shock Absorber Rear Brake Pedal New Bearings Linkage Rerefreshed Dual Radiator Setup Arrow Expansion Chamber (A lot lighter than stock) Polini 160 Big Bore Kit Italkit Pneumatic Powervalve Dellorto VHST Flatslide Carb Lightweight Clutch Pressure Plate I just dropped the frame off for powdercoating last week. Engines out for an overhaul All new bearings and bushes New Old Stock Genuine Fairings New Old Stock Genuine Graphics Kit I wanted to update this thread when I had it in a viewable position. There is lots to update on, but I want to get it in a more showable position before I blog about it.

Small updates, rear sets refurbished and fitted. [image: KZc9g5J.jpg] Brand new OEM Genuine handle bars fitted. [image: PdA0H8Y.jpg] A quick five minutes with the buffer just to bring some shine to them. [image: wIU7bkI.jpg] Switch gear fitted and cables routed through. [image: DQukIxO.jpg]

Late to the party, I must’ve been pissed and missed the post Merry Christmas and a happy new year lads! Hope everyone’s doing well, in good health and you spoiled yourselves a little over xmas

@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

@markus-w Yes absolutely. The SDR200 is a gorgeous machine.

When using lower octane you can always alter your compression,there is an equation to Graham Bell tuning book for that,if I remember correctly. Speaking for our loving tuned DT's,stock ones won't notice it.
