Not quite sure though. Lap times may be interrupted badly by messing up 1 corner. Also another feel to a bike might slow you down at first, so might be misleading. As for battery usage on a few laps. It's a 2:30 to 2:45 min lap on a sandtrack. Just 35/40 minutes is needed to drain the battery...

Another problem is the handler switch connects to the phone mount of the EX. Wich you would also need. That way your phone would no longe connect with your bike. The MX motor will not connect with the EX battery and the other way around. I think in the end to get this working as OEM you might...

The wiring harnas will not fit to your battery. So will not work. Maybe a 12V battery wil do, but maybe not because it needs the VCU.

I pretty much think the big cable is plus and min. The other ones get a signal from the handlebarswitch or VCU getting its orders from the switch. I think the best bet would be to go for an entire wiring harnas and connect that to a battery. However not 100% sure if the VCU is involved. It...

I also found one on the torque that someone calculated from the HP dyno from above video: If we take this to be true one would say the peak efficiency ends at 43 mph/69km/h. If you with my riding involving 70 km/h as is now (and far more when it would be road legal in OTR events) you would...

Well that's a reason why i would love to have a roadlegal Varg. That way you could test under the exact same circumstances. I do have the feeling on the really fast bits (not in this video/track) of ''over revving'' the engine. Almost as if you get past a powerband. Here is a dyno chart from a...

It's a Beta RR 300 Racing from 2021. So KYB in front, Sachs in the back. From 23 onwards they have MYB front and rear and should be a better transition with the Stark. However being an enduro bike it's far softer with all pros and cons. For racing i would love to set it up the same, but the Beta...

I could experiment a little on one off my regular bigger MX tracks. Wouldn't be the best comparison to my races, but at least we'll see a difference if there is any. I have 12-13-14-15 sprockets on stock (shares those with our Beta's). Maybe on a quiet day (so the ruts don't change too much) do...

To reduce weight you could go 19' at the rear. The rim is way lighter than the tyre. The OEM tubes are very light, but i broke the 21' on the first ride and the 18 on the second. However that was the November 23 model. In December 25 i ordered a new 19' wheel and pulled the tube immediately so...

Does that really matter on the lifespan of an MX bike though? Also this is not a circlip mount, but a solid bolt connection. I never seen damaged axle splines on a bolt mounted sprocket. I have seen it with circlip sprockets with both OEM and aftermarket. I think it's more a design feature than...

I used around 10.3% per lap (8 laps used 83%, each lap rougly 7:30 min). However in the fast farmland section i could see it drop 4% in just under 1 minute. So that short sprint eat up an over reprecented part of the battery. In the obstacle section i couldn't catch in right before and after on...

Those damn backwards ''rednecks''. I've been hit by the same rider twice in the same CrossCountry race. He explained he did not hear me. Well i was riding slower in FRONT of him the first time and the second time standing still at the entrance of a single track where a crashed bike blocked the...

Hard to tell though. All these races run once a year per specific track. Most are even prepared for just 1 day and are setup slightly different each year. The race i did last weekend was the same i did a year ago. Then we had snow and hail around freezing with deep sucking mud. This year we had...

To answer my own question: The ''SEX1-P-RF-02-B Rear fender'' came in and i mounted it on the Stark MX. In shape it was a perfect fit. It however missed the mounting for the rear wires of the MX. I drilled a hole to fit the upper mounting and that was all the modifications i needed to make...

Well they got the important bit right didn't they...

Average speed last race was 40km/h incluiding the slow obstacle course where average speed was low going over logs/concrete obstacles etc. In the OTR events that i would run in the future average speed wil be around 60, with top speeds close to 110/120km/h on the corn fields.

Is there a significant range to be won with taller gearing and thus lowering the RPMs? I do 2 hrs races with some of them actually having some quite long fast sections on them where we reach over 60 km/h. I was wondering if adding some taller gearing would help me push another lap out of the...

That happened on the early MX models, maybe they moved away from aluminium after some of those incidents. Stark is quitte good at taking lessons from failing parts. Anyways, it has been common practice by the local Stark riders now to just move onto aftermarket ones. Same goes with the tubes...

On the MX KTM sprockets fit. So you have the range of 12-15. I dislike the Stark ones, they are aluminium with holes drilled tru. They wear very fast and i know some people who actually were able to break them in 2 on hard landings with open throttle, in 1 case bending the drivertrain axle by...

Yess and no at the same time. At very slow crawling stuff it feels lighter (and actually is 10kg lighter), also with near tipovers it's far easy'er to push it back up. But when the speeds go up the superior suspension and stiffer frame of the Stark take over where the EXE880 gets luggish and...
