    @CYBER-NINJA Ohh yeah, the ol' TDR setup is cool. That's an easy job to put on. They are longer forks aswell, bit nicer road manners. Think it's all there on eBay at the moment too.

    Would I have to swap to those forks, in order to run that set-up then? Or will they bolt straight on to my stock forks???

    @CYBER-NINJA Compare the calliper mounts, You need the TDR fork leg to run that Brembo caliper straight in. The DT caliper mounts are wider, I have measurements somewhere :L

    Keep it real

      @Darty OK So ultimately I would have to swap the forks to match the calipers, Ie fit a whole new front end to achieve the best results? Which is an option I was thinking about for the future, so if I upgraded the forks to a sexy pair of USD's, say from a YZ for example, then I could just run their brakes Np's? Providing that the disc fitment is the same of course?

      Will some USD's fit into the stock yokes, or would the whole lot have to be changed?

      Sorry I'm new to all of this [Big dreams, Small wallet, Limited knowledge!!! LOL] ;O)

        @CYBER-NINJA haha same here really, But to fit any new bigger calliper will need a bracket to accept the calliper bolt 1of2 onto the fork leg, because I couldn't find anything thats fits.

        DTR yokes are 41mm, So you will need the bigger yokes for Inverted forks.

        I reckon a YZ/WR early 1990s calliper onto a YZ disc for that year is the best option without changing a wheel or fork. Those YZ/WR calliper mounts around 1987-1991 are not far off. Needs fettling tho anywhere you look at

          @Calum @Darty Thanks guys, the R125 calipers are only 2 pots with two pistons pushing onto the same side of the disc. I'm sure they would be an upgrade over the stock calipers, but I feel a true 4 pot caliper would be more effective.

          I've been doing some research and discovered this lil gem, (scroll down to Nev's post at the bottom);

          I like both of your set-up's and call me picky if you will, but I would prefer true 4 pots and also to have my brakes sporting a Brembo logo rather than an Aprilla one!

          Looking at other models, I have discovered that the XT660R and the DT125X both came with a Brembo 4 pot and 300mm disc. So I'm thinking that may be a good combo to use, as I can also use the front master cylinder from the XT as well? The only part which would need fabricating would be an adapter bracket for the disc and caliper to make it all fit, which is a relatively straight forward job, so long as all the offsets are right or course. The biggest problem I for-see is finding discs which will fit the DT's 3x2 bolt pattern on the hub, Larger 320mm discs are more readily available, which may be a better bet as there's more choice. Plus they may be able to be drilled to match that 3x2 fitment on the DT hub. Does anyone know if the XT/DTX/WR hubs are the same as the DT hubs or not please?

          For the rear I've discovered a matching 2 pot Brembo caliper, from a Ducati Monster, which has a similar hanger to the stock DT one as well. It uses a 245mm disc, so again that may be another good staring point, with minimal mods to make her fit as well?

            @CYBER-NINJA Yeah that's good ol Nev for you. He used to moderate with me and a few others on the old forum, he's a good bloke, very knowledgeable.

            Well let us know how you get on.

            He posted a lot of his findings on the old dt forum, I'm sure that site would act as a goldmine for information

              @CYBER-NINJA I copied Nev's findings to be fair. DTX/YZF/XT Twin Pot Brembo(they are the same) but the XT calliper mount is a closer fit to a DT fork leg. good shout. You should lace up an Alloy wheel and bigger hub man, DT wheels are steel and less weight will improve brake performance

              what ever happened to Nev's TZRRHybrid!?? Was on point

                  @Calum & @Darty;

                  I was looking on the old forum, but a lot of the pictures posted on there are no longer visible for some reason. So I ended up widening my search to get more info.

                  I have alloy wheels on my wish list. I suspected that the stock rims are steel and as a long term cyclist I'm aware of the benefits of ali rims over steel. I have my eye on some nice alloy rims on ebay and discovered a UK company that refurbs motorbike wheels, so I was gonna get the new alloy rims and re-use the existing hubs. I have seen lots of very sexy ali aniodised hubs, but there not that cheap. However new hubs would probably open up the door for a wider choice of discs I guess?

                  What size hubs would I need and which hubs would you recommend please???

                        @CYBER-NINJA please don't buy those. They are way too cheap.

                        Usually wheels are expensive with good reason.

                            @Calum @Darty They look nice and shiny, but I wasn't sure about the quality? Thanks for the advice and links.

                            I am going to keep with the Enduro/Adventure bike look and stick to a 21/18 set-up. I'm an old school BMXer and later on a mountain biker. I always hated black rims with black tyres, the manufacturers went all black for a few years and I luckily had the for-sight to buy a few pairs of skin-wall tyres beforehand, so I never had to go without my favorite rubber. It's Old school skin-walls everyday for me, but sadly with motorbikes the never made skin-wall tyres. I'll keep my eye out for some sweet looking chrome rims and anodised hubs. I'm guessing that Excel, Talon's and SMPro are the one's to have? Maybe some MX rollers will appear on ebay for me some time soon??? LOL ;O)

                              Here's a few pics of the Kyoto Discs and EBC Red stuff pads fitted. They do improve the braking for-sure. With extra bite and shorter stopping distances, the brakes now feel a lot better and give you more confidence whilst riding. They are an upgrade on the stock set-up, but it's not a dramatic improvement as you will need to swap the forks and wheels for that. But an upgrade for better braking and shorter stopping distances is well worth it, even if it's only enough for you not to swallow ya balls every time you have to stop suddenly!!! LOL ;O)

                                I bled my brakes today and swapped out the old fluid for some DOT 5.1. I can happily report that there has been a further improvement in the brakes with a more stable feel to them. With even more bite and shorter stopping distances too. The brakes now feel a lot more secure and inspire more confidence when riding for-sure!!! ;O)

                                  @CYBER-NINJA Braided lines make a huge difference, Cool discs I've not seen those before, could only find a Kyoto Wavy for the back of mine,

                                  Get some Fork Gators on there !!

                                  Keep it real

                                    My bike came with braided lines, so now it's only the calipers which are stock.

                                    There's a couple of dudes selling the Kyoto Wavey discs on ebay, they do give the bike a more modern look for-sure. I got mine from this guy;

                                    http://www.ebay.co.uk/itm/360913524396?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

                                    And my bike also had fork gators on it when I bought it. I hate them as the look ugly and always look dirty too, so I cut em off ASAP!!! :O)

                                      I am running aprilia rs125 brakes and they are unreal! Four pot calipers on the front and dual on the rears. Stop on a dime.

                                      I am also running an Aprilia rsV mille mastercylinder which was needed to pressurise the system. No modifications necessary for that one and that would improve the braking effect.

                                        @xgaryx209 Any year will fit after you have made a custom caliper bracket. Sadly that is the only way any other calipers will fit the DTR hub/disc/caliper combo. 😞

                                          @NINJA True, but I'll take my hat off to you if you get any caliper post 05 to fit

                                          @Dt-r_Bradders Was using that setup, but I don't think he ever finished it,
