A Fairly Complete List of 41mm Forks - These Will Fit Directly into DTR and DTRE/X Yokes :P

[Nottsbiker]

Looks like the 41mm bit is based on the stanchion diameter so bear this in mind when assuming that WR200 USD forks will fit, they wont as the slider part on these is considerably larger than 41mm and wont fit in your yokes. Also FZR and YZF forks will be a lot shorter than DT ones

@Calum so you mean to say if I was to find some relatively good condition 89 USD spec I could save myself some hassle and fit them easy peasy?

[Calum]

I doubt you will find USDs to fit the yokes.

[declan]

@Calum nah you might be able to find the right width but they’d be so short

[Calum]

@declan What like Pitbike USD's

[declan]

@Calum yep

[Stevie Wonder]

Might just have to buy some and send it, give the bike the Raleigh chopper look
Currently during to decide on a half decent set of USD that are capable of giving me somewhere to put the ignition barrel and not give me to many problems running a supermoto set up as well as YZ front wheels

[Calum]

@dtStevie98 Well, I use WR250F forks, same as the 400, and I run SM wheels.

[Stevie Wonder]

@Calum any issues putting the stock 18-21 setup back on with those forks?

[Calum]

I wouldn't know, I never used stock wheels with this setup.

@dtStevie98 The front brake caliper may need a custom bracket manufactured, plus the disc sizes for the old DTR disc pattern is very limited. You would be far better off buying a complete front end off another bike and then you will only have to have a bearing cup made up, to fit them to the DTR frame. That scenario would give you a ton more options and way more flexibility too.

@NINJA thank you, I think that’s a better option. I was thinking last night and I prefer this option it just gives me a lot more flexibility as you’ve said but also give me a lot more flexibility in terms of what forks I run. I was trying to avoid changing the braking setup however considering the amount I complain about the brakes, I’ll thank myself later. I’m more just looking to have the option to throw WR125X wheels on when I want with as little stress as possible.

@dtStevie98 See these threads bud, they will give you some ideas. If you can get hold of the full Aprilia MX 125 front end it will save you a lot of hassle, if not any other bike like a KTM/Yammy/Honda etc can be made to fit;
