      The Chronos Project

      At the time of writing, I currently own 3 Aprilia RS 125s. I've had this one for quite some time, well the frame at least. I've been sorting bits out on it for the last few years, collecting and buying parts that are needed for this project. I am in no hurry to complete this project, time is on my side.

      After completing The Helios Project I was left with an insurmountable of spare parts, enough in fact to almost build a second Aprilia RS. In total, 4 engines, 3 swinging arms, subframes, tanks etc...

      Whilst The Helios Project is based on the ethos of, "What I would have loved at 17", with no expense spared and modified. This bike is supposed to be as it left the factory, although as you'll see later I didn't really stick to this.

      I got this frame in a bargain job lot for £220, it's an older Extrema Frame '98 spec and came with a horde of parts that are completely not needed (back on eBay they went). The result of my endeavours saw that this bike paid for itself, after selling the parts I didn't need.

      You can't complain, for something that was free, however the frame appears to have been in a war zone. The side stand mount had a big crack in it. There were gashes and scratches on the frame and various other affairs.

      I cut the side stand mounts off, and had new piece tig welded in its place. Buffed out the scratches and had it painted matte black.

      It's come out well and you wouldn't know that it was in a sorry state when I got it.

      alt text

      I've ran out of room in my garage, need to shift some of these bikes elsewhere, so for the meanwhile, I'm fortunate to have a spare room in my home to build this one.

      alt text

      Already ordered the fairings for this bike.

      alt text

      A set of Genuine Fakes from Australia (China although they pretended to be from Aus...).

      $900 buys you a complete set of painted panels. I've got to say, this is an absolute steal. The Helios Project cost me a few thousand to find all genuine panels for that, so for around £400 to have all the panels brand new.

      alt text

      The panels are known to be brittle, don't expect OEM here.

      alt text

      The painting is fantastic, the colours pop!

      I can't recommend these copies enough if I'm honest.

      alt text

      How it's sitting at the moment.

      I did order a few genuine (albeit used) panels in some areas as the genuine parts are made of that plastic they use on car bumpers so are literally bullet proof. The new fakes went straight on eBay.

      Along with some genuine panels, I couldn't resist buying some high quality carbon fibre panels.

      Some lovely carbon fibre winglets from a company in Croatia.

      alt text

      Ignore the mudguard, that's for the Raptor.

      I did get some more Tyga carbon, including front mudguard, rear hugger and silencer.

      alt text

      The generator cover is for my other bike as annoyingly it is missing!

      alt text

      No fancy engine work on this build, I am trying to stick as close to factory as possible.

      No fancy large carburettor on this bike (or so I thought), I wanted the factory one.

      To my knowledge, this is the PHBH 28mm round slide. But I was aware that the later models featured EFI. Not sure what that stands for, but I assumed it was something that bolted to the carb.

      alt text

      alt text

      But I was mistaken, actually the later models ran a Dellorto VHST which I managed to snag for a very good price. It was just listed as an Aprilia RS 125 carb and not the model. Managed to get it 50% RRP. This is a special carb that has a throttle position sensor in it. And like the carb, requires a different CDI (which I thought I had so that went back on eBay).

      The carb works with the CDI to change certain parameters on the engine. Lord knows what this means in practice, since it cannot control fueling, just ignition timing and powervalve timings, but I like the idea. I plan on keeping my PHBH carb though, as again it's something I got "Free", from The Helios Project.

      Spare suspension linkage came up really nice with a quick refurbishment.

      A quick rinse on the buffer to remove the dullness from the blasting.

      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.

      @declan That's what the Spigot ring is for bud.

      The problem is, is there enough metal to machine away.

      The options are, weld it up, machine it down Machine it down, make up a spigot ring Machine it down go with the next available bearing size

      For the moment, the bike is again running, so as I say, I'll put the wheel in the loft and worry about it another time.

      @stevie-wonder I would say the Mito is more comfy than the RS.

      The way the panels are inline with the frame, as opposed to on my RS your knees rest on the making it feel rather cramped.

      But yeah this bike is a hoon.

      @lllDennis So my rebuild consisted of Stainless as it's cheap.

      I just got all the bolts for the engine from "Raceti" and that cost me £145. So it's not cheap. And I'm sure you can appreciate there are a lot more bolts than just the engine.

      The thing that hurts is when they rattle off! 🤣
