Sur Ron Climb Hell | Defying Gravity

I'm out in woods, with my friend Lucas and his KTM 350cc. I had just changed tyres (although the rear one isn't new) and for the occasion we're going full on hill climbs.
Throttle management and balance are a must for this kind of exercise. Also, at some point, you'd need a wider rear tyre. This time I really felt that the 19" rear wheel was lacking grip compared to the 18" one in the steeper sections. You can't have it all!

Thanks for the video!!! you make the surron look great!!!!!!!!!! what a ride too!

[@loicdeniau2991]

Très bonne vidéo, ça donne envie de sortir la moto. Et c est cool que tu tourne avec une cross ça permet de se rendre compte des limites du sur ron dans de vrais conditions.bravo continue 👏👏👏

[@MTO_Brothers]

Merci à toi 😁

[@ogasi1798]

by far the most radical riders of these e-bikes on the internet.

[@MTO_Brothers]

Thanks man!

[@zezi1707]

great content i have always wanted to buy sur ron and thats why ım saving money and u inspire me to save money

[@MTO_Brothers]

That’s a very good reason to save and you’ll definitely thank yourself for the effort as soon as you ride it 🤘

[@darghmido]

chacune de tes vidéos vendent du rêve ! j'ai comme objectif d'acheter un sur Ron, déjà fais l'essai et la demande de prix, maintenant patience pour avoir l'argent^^ continue t'es au top en tout cas !

[@MTO_Brothers]

Merci mon gars ! Ta patience sera largement récompensée par le plaisir que tu auras à chaque ride. Lâche rien et va jusqu'au bout 👊

[@tornadogti959]

Ah, so nice and smoothe riding. Still waiting for my 72V battery. Nuc24F is installed and I'm ready to go. Even with the stock battery the nuc feels great 👍🏽

[@MTO_Brothers]

Yeah the Nuc is such a great improvement. But you'll see, when you get the 72V you won't recognise your bike! By the way, where did you get the 72V from?

[@tornadogti959]

@@MTO_Brothers I’ve bought the 72V from Zemso in Germany.

[@daveman961]

Hey! great video as always! got a question regarding your battery, how did you build a 72v battery so small it can fit in with the stock lid-cap greetings from austria

[@MTO_Brothers]

Hey man! Technical speaking, you just need 20 cells in series and you have a 72V battery, it'll have only about 3Ah, but you still have a 72V! This one is a 30Ah (20S10P), so it's about the same capacity as the stock one. It's small because it doesn't have that many cells in it. This is a prototype as I'm working on manufacturing a line of batteries 😉

hahaha oui, racines plus grosse ornière le tout dans une sacrée montée ! Avec les grosses roues ce serait peut être passé mais là je me suis tanké direct j'ai même pas essayé 🤣

Excellent Content and I'm sure you have done this before ,Great blog

[@ridefarm5528]

that's such a deep rutted climb!

[@MTO_Brothers]

Yeah that's crazy! Without the rut I might have made it straight

[@fnixx1366]

your friend sure knows how to ride his bike!

[@eowasakicod6691]

Super vidéo continue comme ça. Tu as gardé le moteur d'origine pour la booster a 13kw ?

[@MTO_Brothers]

Hello! Oui c’est le moteur d’origine, il tourne à 15kW en puissance max.

[@michaelscott466]

Lucas left you in his dust!

[@MTO_Brothers]

hahaha, if you say so ;)

[@cometomicke]

Awesome stuff. Really enjoyef that. You ride really fast. Is it very illegal with the 350? Are the surron legal over there?

[@MTO_Brothers]

Thanks mate. Yes in France enduro bikes are legal as long as you’re on a track/trail and not in a restricted or protected area.

[@cometomicke]

@@MTO_Brothers that is really cool. Here in south spain it is illegal to go in the countryside but everyone does it anyway. But i hear there are large fines. So i guess France sounds better then in that aspect anyhow 😀👊

[@MTO_Brothers]

@@cometomicke I guess so! How come it's illegal? Like completely? Is it just in the south? In Cataluña the rule is: if a trail is large enough for a car, it's legal (that's the theory).

[@cometomicke]

@@MTO_Brothers every county or province or state has their own rules. Andalucia has some strict rules and the reserves are stricter. But it is actually not very easy to read the rules. Firestreets are illegal, but everyone rides them. The police has fined people. But guys have been riding for many years and never had issues. Wonderful trails anyhow and the countryside is enormous

[@MTO_Brothers]

@@cometomicke Yeah I love Andalucia but have never ridden there. And it's definitely on my todo list. There's no way I can skip that for 2022!!

[@girodynamics1597]

HI BUZUT , WHAT REAR TIRE USE IN R19 ?

[@MTO_Brothers]

Hey man. I change a lot. What’s your usual riding terrain? Rather rocky, sandy or muddy?

[@raphaelptak5949]

Ahahaha comme ça pousse ….tu me rends dingue avec ton avion de chasse…

[@MTO_Brothers]

hahaha, oui ça pousse pas mal. Je m'en lasse pas 😝

[@Ron-don]

Nice bike if your filming with a go pro could you switch on gps so we can see speed ur going and all that

[@MTO_Brothers]

It's a GoPro but it's not working. I've tried but GPS speed is completely off in the woods.

[@sturzpilot3374]

great video keep it up

[@user-uz8cg8hc6f]

Did you modify the bike or its official intention from the company?

[@MTO_Brothers]

It's modified mate. More power and some upgraded parts (braking, suspensions…)

[@user-uz8cg8hc6f]

How much did it cost you?

[@MNnytrorider]

You in Quebec?

[@MTO_Brothers]

Nope, I'm in France!

[@MNnytrorider]

@@MTO_Brothers awesome. What part of France is this? I hope I can get there soon.

[@MTO_Brothers]

@@MNnytrorider It's close to Lyon city. If you're around visiting that's also a really nice place to visit and the world's best place for gastronomy 😎

[@Brakzer]

mon pote tu devrais te faire une 16" à l'arrière. c'est pas bien lourd et autant de traction qu'en 18 !!

[@MTO_Brothers]

Oui le 16" accroche fort mais en fait je crois qu'il est un peu plus lourd que le 18". Car le pneu est beaucoup plus haut que le 18" ou le 19". Les trois tailles de roues étant presque à même hauteur une fois les pneus montés. J'aime bien le 21/18, mais c'est vrai que venant du VTT, la sensation de maniabilité des 19" j'adore. Donc je garde les deux, chacune pour un usage différent 😎
