Just curious on the group’s opinions between the bikes yesterday. I think if the rain hadn’t started Kenny wins it, him and JB were on it all day. Marv is smooth no matter what he rides but I think the power delivery of the TBi was the advantage he needed on the slick hard pack.

Rain ruined Hansen´s run even he was on TBI bike.

His timing mistake wasn’t the bikes fault.

I thought the efi bikes launched out of the gate better all day ,

Marv was getting better all day

I've got to say, it did pop into my head and I'm sure there are subtle differences.

With folks of their calibre and experience and how those runs went down, I'm not sure I would say it factored into the results though. Maybe I'm wrong and it did play a part, it is an interesting thought.

If I was playing devils advocate I'd kinda be on the same train as Scott, they did look a little more tractable, which is their touted improvement so it makes sense, but who knows when it's different riders.

It had no effect. The only thing that affected the outcome was different levels of self preservation from the riders causing some to chill more than others when the rain came.

I was wondering the same thing. I know which I’d rather have in slippery conditions. But I’m slow. For these guys I don’t know if it’s a factor but it’s an interesting question.

Does anyone have insight on how modified the tbi bikes were compared to the carbureted bikes?

Even before the rain, I thought the injected bikes appeared to drive better both out of the gate and through the whoops.
But there’s too many variables to know for sure.
Did it effects the outcome? It may have been a factor, but Marv was simply too good in those conditions to take anything away from him.

I think so too... TBI bikes had an advantage out of the gate, especially in the wet conditions later and also imo more visible on the 125´s...

The fuel injected bikes were clearly faster or hooking up way better ....every single one of them pulled a quick lead out of the gate till the rider made his own mistake. It was consistently better

Marv said in his post race interview you have to ride the TBI bike different than a carb. He didn’t elaborate and I bet KTM wouldn’t want him to say anything, let alone more, if there were deficiencies compared to carb. Which I infer since he said “different “ not “better”.

It was a 300 ktm vs a 250 Yamaha.

No replacement for displacement

Displacement was much more of a factor.

Looked a bit similar to when Villopoto rode the PC YZ250 against the KTM 300s a few years ago - if you don't think it makes a difference, try riding one.

I thought the KTMs were all 250s this time?
150s were allowed in the 125 class, but no 300s in the 250s?

No it wasn't, they stated no 300's this year.

Thought i heard one of the ktm guys talk in one of all the videos in the background saying that the bikes were stock with exhaust.

If that is the case, the broad oem powerband with probably a more mellow hit than the PC 250 bike would help to get out of the gate..

On the Weege posy race show Jade Dungey claimed the KTM's were pretty stock and they did not have much time on them.

Pulling a good start on a 2-stroke from a grate to a slippery wooden platform with water on it is harder than it looks. (See: Justin Barcia almost not making it over the first gap off the platform.)
I'd bet it's the riders' relative inconsistency with a different starting routine, on unfamiliar bikes which could have been a factor off the start. Especially once it started raining.

Just an observation, the cat who won the 125 class was on a carbureted YZ in the rain. I am in the middle of a mental battle over if I want or need a '23 TC125, so I am not bashing that at all, but just pointing out a relevant truth in this discussion.

Marv said they were riding 250’s not 300 for anyone wondering.

Well then, I am an idiot of that is the case :D I ride the same tracks locally and he has been on nothing but YZs lately, YZs for WMX, I am surprised he was on a KTM, I just noted BBR logos and didn't look closer. If someone can jump on 4 different bikes in a week and win on all of them, he is the guy that can do it.

Sorry for looking like an idiot here, I didn't think he would be swapping for RBSR, clearly I was wrong.

Seems like the factory KTM/Husq/GG factory riders weren't too confident when they spoke to Swap.

Might have been that the 250 2Ts weren't comparing well to their usual 450 race bikes on a gnarly track. Or maybe they didn't have the injected bikes figured out for this yr, which wouldn't be a surprise given they are new and there was a TON of privateers struggling too:

He had both a YZ and a KTM at RBSR. He rode them both in practice, but decided to race the KTM. The YZ was a 125, the KTM was a 150.

Lack of seat time. They only rode the bikes a couple times before the race. Marv had never raced a 250 2 stroke before.
