Good review !! This mix of bikes and riders is an awesome way to test !!

[BrendonMills]

Why doesnt Yamaha make a GYTR edition YZ250F and YZ450F? Similar to KTMs Factory Editions. Would be a great option for someone looking for a complete ready to go Mod 250F and makes good sales for GYTR

Wow that GYTR bike looks really nice, if I ever had to replace parts in my motor id do the GYTR kit instead

[torr-michaelbennetta]

I had a GYTR250. Amazing Vet bike. Light feeling, with plenty of engine to ring out. GREAT compromise between 250/450. Would get one again in a hot second.

You make a great case for a 283cc big bore 250 with the GYTR cams.

Love, love my YZ250/IT465cc 2 stroke best of both! I smile just thinking about it.

I have taken in four Yamaha Demo Days at different MX tracks and have owned six Yamaha bikes of various types. On two occasions they had a GRTR YZ 250F alongside the stockers and my opinion is that the GYTR bike is more mechanical, more hard-edged, than the stocker. Me being a mod-C class guy would not really benefit from that modded bikes higher revs, as I don't rev my bike that much anyway. The stocker always was more plush and that is what I like. Great comparison !!!

Awsome vid thanks for all the info ML. 👍👍

[mikeb]

How about the GYTR engine with a dual injector kit?!

[jeremys]

Should do a mod and stock 250 2 stroke vs the 250f’s

[cristiannaser]

Is any photo of the mellow map you mentioned of the 450

[Moffattfamily-]

So would a big bore be better cost wise it’s cheaper. Would it get closer to 350?

[rokuabtor]

You should have had a Husky 350 in that Comparison Test!

You can always detune a 450. But you can't uptune a 250. For bigger riders or vets that have already been riding big bore machines. There's nothing to be spooked by with a modern 450. It just needs to be set up properly, and an ECU map loaded that's manageable for the rider.
The way my '21 yz450f came from the dealer, it was basically a death trap. Virtually unrideable. I had to go over the whole bike, front to back, top to bottom. The power was completely unmanageable. That's the biggest consideration when deciding on a 450 or 250. If your not a good enough mechanic to keep a 250 running in a controllable manner. Then a 450 isn't for you. More power can only benefit you, if it's controllable. Figuring out how to keep over 60hp from killing you, can be a challenge.

[halvorsonmx]

what is the actual hp difference between stock and gytr? I can't find that info anywhere

[kochj]

why is it that you can push deeper in the corners with a stock bike that has been broken in? find the reason and put that in the new bike

[carverac]

If someone wants a Japanese 250 closer to the KTM 350, don't go GYTR, go big bore

[hannesleijowall]

I wonder what maps the where trying on the 450. I mean if u run a mellow map on the 450 it is not that hard at all to ride. Its a different riding style! Cant be as aggresive, and if u are a 250rider yeah well.

Also you where running glenn hellen. Hard to grasp you didnt beat the laptimes on the 450. I bet it cuz you where not used to the 450.

Lol Darkside is an awesome part of VitalMX. ML and Dark is a great combo!

Why is the girl in the middle have a beard?
