 Here is a list of Yamaha TZ parts For now it is a place hold for images, I will update this shortly. TZ250/350 C/D/E Fuel tank rubber damper mounts Check out the item available now on eBay . TZ250/350 E/F/G Fork top caps

 Here are some examples of products we have made that fit the Honda CBR400 (among many others). Fuel tank side cushion 17516KAZ000 Shown on a Honda NSR250 MC28 This does not come with the adhesive tape you would find on the OE part, as it easily washes off when fuel is spilled on it. We leave it to the customer to choose to use tape, adhesive foam or to use a more appropriate glue like 1300L. Stem cap Initially produced for the CBR400 we soon found out this cap is common to a load of Hondas that were both designed for this cap and also for those that were intended to have a capped nut fitted. CBR400RR NC29 VFR750 RC24 Efforts were made to add strength during shipping to our product by designing in support material that could double as packaging. This has had some success but cannot protect from abuse. It still is a great example of a production, normally disposable part, being reused in the packaging process. Sub air filter This sub air filter fits over 765 Honda models from the 80'

Intro Here you find some products we make derived from parts that were OEM on the  1982 Yamaha XT200. Chain guide The Chain guide is not unique to the XT200. It is also the OEM part on the XT125, XT400, XT550 and DT125LC. We took inspiration from the OEM part and made a few improvements along the way. The silhouette remains the same whilst a 3D printing optimised front face makes for a clean look that both looks clean and suits this classic motorcycle. The inner arm is offset inward like the OEM part but it is also  slightly angled so it doesn't suffer with chain rub as badly as the original did. We have also chosen to print this in PETg, a material that wasn't really an option back then and offers superior resilience whilst being 100% recyclable and by virtue of its hollow design, lighter too. Most of these details could easily go without great fanfare but what most will be more excited by is the fact that we can offer this part in a wide range of colours and other materials t

Intro A friend of mine had complained about loosing those silly little caps from his Nissin callipers and then faced the issue of not having them fitted ie. seized calliper pins. Design A quick potter about the workshops  looking for a loose calliper and I found the part I wanted on the NSR250 MC28 as I popped in for a brew. A short while later I had it measured as an M10/1mm and 15 minutes later I had finished my brew and the printer was making some noise. I could have had them done quicker but first time round I wanted to add the dimple in the middle of the slot which I quickly binned to add strength. I made them long at first to add some meat but was the over hang just makes them look loose so I cut them a bit shorter.   With the length about right I was basically done. Printing in CF PETg for heat dissipation, I changed to PETg as I didn't want to cause difference metal corrosion (yes carbon is in that chart). This however was a bit soft for my liking so went with ASA. Thankful

  Yamaha FZ600 Chain Guide Swingarm Protector fig1.1 - HPE chain guide for Yamaha FZ600 Intro We have produced a chain guide / swingarm guard for the Yamaha FZ600. Our version of this part is produced in nylon, not the traditional rubber. This takes best advantage of an FDM 3D printer by using a very hard wearing material which allows us to produce a cheap and long lasting product.  The chain guide features increased wall thickness to allow the already highly wear resistant material to last even longer. It is worthy of note however; that a poorly adjusted, unlubricated and/or rusty chain will make short work of eating through any chain guide. Fitting Guide Fitting the HPE FZ600 chain guide is best performed with the swingarm removed from the motorcycle. See it as a good opportunity to clean off old chain lube goo and to regrease those swingarm bearings. Place the tophat washer on the inside of the rear bolt hole. If your top hat washers are missing, take extra care later when tightenin

I am fortunate enough to own an upper mudguard for a Yamaha TZ250/350 C/D/E chassis, it came with my TZ chassis, but I knew I could quickly make a copy and other wanted one without spending upwards of £90 on it. A quick scan and an hour or so spent on Fusion 360 later and I had a workable model. I only required a couple of minor alterations to get the frame to fit perfectly, then a PLA copy of the rubber guard itself was printed to use as a template. Second print in carbon fiber PETg Once the rubber arrived (I opted for 1mm rubber sheet rather than the OEM 1.5mm to add some lightness) I cut out the first sheet and rough assembled the guard using M3 cap head allen bolts. Annoyingly I hadn't made any alteration over the OEM guards okay fit but it works as advertised so remains un altered for now. I actually quite like the cap head allen bolts but with the risk of them easily vibrating loose, I decided to finish this guard with pop rivets. These are light weight and are more true to t
