Nice one Calum, those wheels look terrific

[Calum]

@oldman They look better with the rubber on, better contrast between the red you see.

I'm just waiting on spacers so I can fit it into the swingarm, which should look really nice.

[Irongamer727]

@calum what do you think is the maximum output for a tuned rotax 122? 45 hp+?

[Calum]

@irongamer727 On race fuel with countless thousands spent on it. Maybe.

Pump gas, I'd say 33-35. GP bikes probably just shy of 40.

But then remember it's not all about peak power. Power is no good without torques. And this, whilst being superteen imititated, is meant for the road, where torque is so much more important.

So, whilst I will be getting the engine ported, it'll be for road tune.

45+ no chance best I saw online is 45 bhp by some crazy guy with no sense and too much money he was from Italy I think I can't find any info on it anymore shame not that anyone would do the same unless they were rich and enjoyed rebuilding it daily

but people get 28 bhp all the time 35 has been reached by many

she looks a stunner in bits beautiful bikes swing arms are a piece of art thank god you didn't follow the crowd and polished it I found that Continentals Conti Attack 2 feel better on rs duo to the bike being so light the angle helps in corners and there great in the wet to maybe give them a go on your next set

looking forward to seeing progress

[Calum]

@terry-tz Hey cheers mate.

You know what, I have been looking at builds and have been told that I should have polished it. It's nice to hear you think otherwise.

I know keeping it clean is going to be a nightmare. But I really think it's a once or twice a year bike so it shouldn't be too hard to keep it mint.

Yeah, also note that different dynos give different readings. I think what really matters is how it performs out on the road, for a road bike that is.

[terry.tz]

@calum agreed follow me so I can message you it came up with an error

[terry.tz]

wash every time you use most probably

[Calum]

Chipping a little more off, but money is tighter than I was expecting.

Got some lovely bits in the post, but can't use them just yet.

Light weight Carbon Fibre sprocket cover. For an engine that is no where near built.

Light weight captive wheel spacers, some 100 grams lighter than the original, well every little helps.

As said, forgot to grab the photos of the wheels with rubber, helps the camera pick up the actual colour of the wheels.

I get it won't be to everyones taste, that's fine.

Rear linkage mated to the dog bones.

Counter sunk stainless steel hex head bolts for the seat lock. Won't be seen but at least I know it's fresh!

Battery box fitted to the brackets. Very snug fit with those new grommets.

All fitted to the frame using high quality titanium bolts.

The rolling chassis so far!

It's getting close to being able to wheel it into and out of the garage.

[terry.tz]

@calum she is becoming a beauty

[Calum]

@terry-tz Cheers mate

Long way off anything being anything yet.

[oldman]

That's better! Those wheels look tremendous, a man after my own heart! Also replace bolts and fixings with quality even when they will never been seen, will be one of a kind completed.

[Calum]

@oldman Unfortunately, one of a kind, it will not be.

As said, these bikes are used for the Junior Moto GP racing, or were used rather (replaced with four strokes today).

So these bikes tend to get built to an exceptionally high standard. I don't have those sorts of deep pockets, but I will do my best where I can. It'll be SuperTeen Inspired for sure

I just need the right sized circlip for the front wheel then I can put the forks and swingarm on.

Hopefully next weekend.

[Calum]

A few little bits arrived for me today.

I got this exact disc on my DT. It was absolutely lovely, and was £60 cheaper than what I paid for it, so I jumped at the opportunity.

All fitted to the wheel using Titanium bolts.

Genuine handle bars and switch gear arrived. Plus Titanium wheel nuts and aluminium fork top.

Thinking of getting the handle bars painted, to contrast the white triple clamps. Then I can look to assemble it. Got some titanium handlebar bolts with these as well.

I've also redone the swingarm bolts with titanium, which was expensive. But it feels nice to chuck the money into this vehicle as it'll be a real nice sunny ride.

Although, I totalled the cost of the remaining parts, the price is eye watering. I think you could have bought two of these bikes brand new from Aprilia for the cost that this one is looking at. But of course, this will be far superior spec.

@calum only a few emojis seem to be working

EDIT: nevermind, they are now :thinking:

[Calum]

@irongamer727

Works fine for me.

You have to give it a while. It uploads it to my server, which uploads it to imgur and then embeds the link. So just because it says 100 percent that just means you have uploaded it to my server

[Irongamer727]

@calum where do you buy all of your titanium screws? Ebay presumably, but from whom?

[Calum]

@irongamer727 Company called raceti

[Calum]

TYGA Rear Sets arrived...not cheap and didn't come with titanium bolts. So bolts ordered will let you see it on the bike when the decent bolts come.

[Irongamer727]

@calum those titanium bolts was NOT cheap!
