MiniGP Build

A month or so ago I tried to buy a no fluids NSF100, but the bidding was out of my price range. I’ve read about them for years and wanted one, but they don’t come up for sale very often around my area. I had no intentions on keeping this stock, so it’s probably best I didn’t buy it since it’s never had fluids and HVAC stored. But the experience reignited my craving to build something similar and I had already been kicking around ideas on what the next project will be. After losing out on the NSF, I thought about getting a Gen2 Grom and fitting some NSF aftermarket bodywork to it. Running the numbers, they're close in size and is doable, but the end product would be something that only looked track-worthy. After looking at several aftermarket fairing options I came across this track bike.

After 2 “unique” bike builds in 2022, 06 CRF50Z and the beloved 22 Hayabusa, it only made logical sense to build something that was a hodgepodge of both bikes…kinda…. A MiniGP track bike! Already knowing the process already on how to register a non-VIN vehicle in Louisiana after registering the SLC, I talked to the same Trooper to make sure my idea was legally feasible. Yup, all is good. This doesn’t apply to all states, but for mine this so called process requires 2 separate trips to the main DMV in the state, which for me is about 2.5hrs 1-way drive plus DMV time. I’ll post about the full process as I get to it, not horrible…it is what it is.

Purchased the 2022 Kayo MR150R on 3/10/23 received about 10 days later. Like the NSF, the Kayo checked off all the boxes for me and seems to be a great blank base for a project. I dig the bodywork, undertail exhaust, MotoGP or normal shifting, electric start (optional), roomy cockpit (for what it is), solid engine and durable bike overall. Visually the one thing I wish it had is a trellis frame. There are some aftermarket parts available, but like the Gen3 not much. I do believe I will be able to source other aftermarket parts that aren’t specifically for the bike, but will fit.

While I’m building this for the experience and it will get ridden a little, one of the main reason is an attempt to learn 3D modeling better. Goal is to do as much digitally as I can; starting with a full 3D scan once I have it running.

List of parts planned to design:
Winglets (yes no point)
Ram Air Duct?
Headlights, discreet R1M-style
Tail Sliders (if needed)
Heel Plates
Inner Dash Panels
Gauge Bezel/Panel
Brake Caliper Ducts (ehhh)
Taillight Bezel
Hump Backrest

For what this bike really is, a $3k bike, anything I do to it outside of tracking it is overkill. But that’s the fun… and I plan to go all out to make as clean as possible, with some technology. All cable/wiring as tidy as possible and hiding as much as possible. Instead of just wiring it up the old school way for electronics, I am installing a MotoGadget M-Unit to control everything digitally. It also allows me to not need a key, only need my phone in my pocket, to start the bike. Added benefit is the alarm so will have protection as well. Mo.Unit does several other things that are pretty slick and will be useful.

With the busa, I don’t even bother making mine lighter… but will do just the opposite with this little bike, MotoGP inspired after all. Replacing the +0 arm, subframe and fairing stay with aluminum versions. The electric start addition adds very little weight when you remove internals not needed. I’ll also need a battery for the streets anyways, and it comes with a 500g (1.1lb) LiPo. I also have front/rear titanium axles, nuts and rotor bolts. I will swap other hardware out for titanium as well. The weight as it sits is 191.3lbs. I had pictures of the scales, but must have deleted them.

As of now the end bike will be Italian-inspired. I’m unsure how the bodywork will end up, but plan to modify it to suit the build when the time comes. Definitely will be MotoGP inspired.

I’m still unsure what it will be called, maybe Traccia Superleggera, Track Super Lite. At the moment it’s just referred to as the MiniGP. And when it gets the license plate, that’s what it’ll say.

Have not ridden yet, only have cleaned the tank out. Still need to flush brakes, refill, check lifter clearance and adjust carb. Hope to ride this weekend.

Few parts were ordered and arrived. Test fit a generic headlight I had laying around and while it actually is the right size, not going to use. It's a track bike that's street legal, so will follow suit with similar style as the Ducati Panigale V4 or the Yamaha R1M for styling influence.

The normal mods will be done before I get on it, then the fun starts. Quality is pretty great out of the box, much better than I expected. I can definitely see why they're so durable, ran hard and put up wet.

I'd given anything to have 2 wheels when I was 11/13! I was always told I couldn't until I was out of the house, which was done and never looked back, lol.
 
Took a while to find something small enough to be feasible to use, LED, good light throw and a nice cut off. They're 1.5" Bi-LED projectors direct from China. I'm running 2 of them so Bi-LED wasn't needed but is a nice bonus. They are not sealed so will have to design an enclosure as well. Unsure if I'll do a DRL or not

Not many options for an aftermarket exhaust, but I located a potential replacement muffler from China and took a chance for $100. It's not real and I ordered it plain, but guess if has to have a logo it could be worse. It'll remain undertail so the tips will get chopped off. I'll build a shroud of sorts as the new tip and it'll have my brake light integrated into it, or at least that's the idea at the moment.

Couple more of the muffler, just zip tied to the subframe and tail tossed on.

Ended up going with the Koso RX4. It was way more than I intended to spend on the gauges, I had been looking at generic universal ones that actually looked pretty nice. In the end, in my experience it's much less headache to install name brand cluster. Not like this bike will get alot of road time but it's got Bluetooth and will display incoming calls and music.

One last update.

I've ordered replacement titanium hardware for the entire bike, every last bolt/nut/washer I could find to measure. I didn't do the engine case bolts and swingarm bolt/nut, yet.

$130 shipped from China with plenty of spares. You have to read carefully on the listings, some are actually titanium alloy. I dont expect these to look McMaster-Carr good, but real. I'll see in a month or so.
 
Here's an interesting tidbit I learned last week when trying to spec out suspension components that had potential to fit this thing....

Most everything I found was upgrades for high end mountain bikes, including prices although they look sick and should act the part for sure on the MiniGP. I see no reason they wouldn't work and be an upgrade if use the correct spring rates.

The rear shock I'm looking at is a US company that I've been talking too about things. I'll let them pick my spring rate for it, figure their choice is better than mine.

Round 2 for heel guards, still experimenting since these rear sets won't be used in the end. I printed my first object in TPU last night and it may be a game changer for this mold stuff... At least playable for releasing it.

Also ordered a few goodies from the UK I'm waiting on.

Trying 3d printed mold in TPU for heel guards.

Cleaned up the shop and organized the cart for the MiniGP stuff.

Modified the KRP aluminum gauge mount to use the koso RX4 gauges using it's bushings as well. 10mm gap between the RX4 and windscreen.

While waiting on my suspension, going to put the fairings back on so I can 3d scan it. Wife's birthday is coming up and she desperately needs a new laptop......as do I so I can bring to the shop and scan.

Speaking of.... My wife hasn't noticed the extra motorcycle yet. Don't think she will, she sees me tinkering with it, lol.

Titanium hardware came in and organized. This is the only scale I have, will get a smaller one, but at least gives an idea on weight difference

Button head was M6x16 black stainless 316

Sockethead was grade 5 steel and 2mm shorter than Ti.

Nut was black stainless 316

I haven't updated this in a while but have been busy working on it. Will work backwards from tonight and catch up soon on progress made.

How durable would a carbon fiber shifter be? Going to first make the one, the whole thing out of forged carbon. 2 downsides is obviously if bike is dropped it'll probably snap the foot off and it would likely be a one time install only unless I can locate a matching splined bushing to bond in. Since a long ways away from riding it, decided to test it out on my CRF50Z. If I do make one for the MiniGP may use an aluminum foot for bling.

The blue one was first print to test fit and verify fitment and angles. The CAD drawing has splines and potentially the part ill draw the mold from. Unsure of brand, but have had it forever.

To help explain a little better what's fixing to go down... Will do the same as I'm doing for the rear brake reservoir currently since the new one has one. Draw a mold of my part, print in TPU, few coats of release agent, layered in 1/4" forged carbon and epoxy measured accordingly. Vacuum bagged, added male side and put in a vice. 24hrs later popped out, trimmed, initial sanding and a full wet coat.

3d printed pieces to design my exhaust routing. If you'll notice the gold colored shock and yellow spring... Ohlïns. When I was trying to spec out a shock, after alot of research found one that would fit and got the matching spring.

Back to the 3d printed exhaust... Found the design online so printed a bed full of each size in different colors. Was pretty fun assembling. I drew the muffler to say I have a full 3d printed exhaust.
