Elevation and water weight is your friend. Statically, kinda, water pressure increases .7 psi per 12” of elevation, this is compounded with water weight and the elevation of said water weight. If I was building an automated sprinter with a holding tank, ... more »

That’s Geeks rig, #18

I have the full big bike a mini kits, this Baja no pinch design is a rim scratcher, it’s horrible

Figure out what type of brain your kid has, most kids just want to ride with other kids who have similar speed, that’s how we started about 4 hrs ago. Took him to the lame Jordan River track about 30 times for two summers, then he got fast and wanted ... more »

Hayden Roberts, aka REP MX

Talking with folks who work their, a daily order average number of 1500, went up to 8000 a day since this covid thing, they simply can not keep up right now

I’m 6’4” with a long torso and long arms. The big Yamaha fits me the best. I buy the widest and most square bar, maybe a 3/4” rise, and kinda scoot the grips about 1/4” on each side to make em wider, or my outside wrist area hurts.

Ummm, it’s a $5,500-6,000 bike, folks spending that kinda money on a fiddy are only looking for a Loretta’s plate with a 4’ tall 8 yr old... lol

I know a kid with one, he likes it much more than his cobra 50, it Visually looks much easier for him to handle, his lap times are a solid 10 secs faster... however, on full power he might get 15-20mins out of it, then, with a 120VAC power source, it ... more »

As a weekly 85cc moto dad, I do not understand mini dads all juiced up behind a PW50. In a real race, this pile of crap has to somehow navigate a track that’s been best to piss all day, The poor kid has to use horrible body positioning and basically ... more »

Stupid poor piece of crap!!! - in Eric Cartman voice

Maybe, a newer ktm big wheel 85 with the 105cc OEM kit, it’s a ripper, and it’s very reliable

Why in the damn deer shit does this forum have some many sallys focused on gear sets and what track snack factory rider Mc whogivesashit is humping? It’s weird!

it’s a tough question. If the kid is not racing a real track race, I’d get a cheap/light MTB helmet, they offer full protection but don’t help much in a high speed crash into a brick wall or whatever. Seriously, the PW is a slow pos, no way is a kid ... more »

Depends on model: 2017 was the first year of the new 85 limited to the white bike, updates came on the 2018 Orange 85.... I’m expected a fuel injected 2021 85, er hoping

I’m a moto dad.... the modern KTM 85 is 10 times the bike over a yam/kawi. both in stock vs stock and the reliability department. And you’re comparing cast parts to billet parts, silly goose. Just because you flip burgers, does not make you a ground ... more »

“KTM haters” are gayyyyer than KTM fanboys, like, waaaay more gay
