HPE - Heggs Performance Engineering

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
