The Helios Project (Aprilia RS 125 Rotax 122 Biaggi Race Replica)

[Calum]

@darty Once I finish the project I shall reupload and reformat this project to somewhere else. It's a shame, you would have thought Google would have been nice and simple.

Another few hundred quids worth of parts arrived today.

Like I know it doesn't look like much, but the achiles heels on these engines are the balancer cogs. Now mine do look like in good nick, but I wouldn't risk it. So new cogs were ordered.

The engine is pretty much built and ready to drop into the chassis. All but the clutch since they're out of stock everywhere I look.

Engine is pretty much built, although I forgot to order a crankshaft seal so I've turned my attention to the other side of the engine whilst I await the new seal.

I reordered the rest of the bolts for the engine Total overkill but I dunno, kinda feels worth it.

It certainly doesn't at the minute... :face_with_tears_of_joy:

[Calum]

@mightyman I literally do not understand how Google could get something so wrong. It's not rocket science!

[Calum]

For you perverts out there, the chassis is now rolling!

I was going to drop the engine in, but a friend needed my Jack, and I kinda wanna build that separately. Will make maneuvering the bike a little easier as well.

@calum If you fitted a crank, some pedals and a chain, then you would be ready for a ride!!! :smiling_face_with_open_mouth_smiling_eyes:

Looks mint tho bud - top job indeed. :thumbs_up_light_skin_tone:

[Calum]

@ninja My mate offered to give me a quick push up the road to test it out, I gracefully declined, despite the tempting offer...

@calum you forgot to put NSFW lol

Lovely job that Calm, you must be pleased with how it's turning out, looks awesome, very impressive

[Calum]

@oldman Means a lot coming from you Considering how immaculate your builds are.

[declan]

@calum very impressive this is id love to have a go

[Irongamer727]

Could you bring it to Oxford sometime between the 18th of June to 1 of July? I'm going on a language course then.

[Calum]

@irongamer727 I doubt it'll be done by then lol.

[declan]

@calum I think we should all meet up just to ride your bike lol

[Calum]

@declan Shotgun going on it first!

[declan]

@calum I’ll ride bitch on the the back lol

[Calum]

@declan Uhhmm, did you not see I blanked off the Pillion seat mate.

[declan]

@calum I did but I’m sure it will be comfy enough or I’ll get a metal basket for the front and we can just go straight ET style

[Calum]

@declan Uhmm, let me think about that...

(Calum is typing...)

[declan]

@calum lol guessing it’s a no then

[Calum]

Everyone I asked about whether I should or should not, said should NOT!

Are they mental...

What's in the box!

Bare in mind, I only want a few components out of this box that are no bigger than a hammer lol!

Any ideas?

If you guessed a kickstart, then you guess correctly!

And I know what you are thinking. Why?

Well appreciate this, this bike ain't an everyday bike, chances are, when I do eventually come to ride it, the battery is going to be flat and I'll have to bump it. Which, no I ain't doing.

Plus, it's totally bad ass crosser stylie yo!

On a serious note though, £600 for the kickstart from Aprilia. I kid you not, it's genuinely cheaper to buy a whole engine (if you can find one) just to salvage the kickstart out of it.

This would be my third Rotax 122 engine for this single project. That's, uhhmm, expensive.

I am going to strip this engine, salvage some of the components, sell the rest.

I want to go all out on a special conversion (for no other reason than because it will be cool) on this bike.

And I'll give you a clue, having a spare engine is going to be useful.

I will gut the cases and leave what I want to modify in place. And hopefully have something to document.

Eventually I will rebuild the cases and store in case of the inevitable happens.

This engine comes out of an Aprilia MX125, ETX125 or RX125. But all of which are really hard to source and expensive when you do. That said, I've got this now, and it's blown the budget for this month, which is a shame. But such is life.
