4 bars is the optimum temperature of the engine. Any more and it's overheating and the fan will kick in to cool the coolant liquid.

There's no flow of cool air in signals since the motorcycle is stationary and ambient temperature rises. Hence, the fan kicks in often at signals

Regarding the coolant reaching the min level, if the odo is under 1000kms and not topped up earlier, then it should be fine since from factory, they're filled somewhere around the minimum mark only. As you have topped it up now, see if the level dips again after a few hundred kilometres. If it didn't, then you should be good to go

Went out on a 270km trip on Saturday with a group of BHPians (4 bikes and 5 cars). On the way back, took the bike up to 7k RPM in 6th gear for a brief period. Odo is at 707 kms now. Some pictures:

Update on the Fuel X Pro: After extensive riding with the fuel x pro in the 5th, 6th, and 7th setting/mode, I felt that the smoothest and almost no jerk in the 7th setting with stock bike. It is only in the lower rpm range (up to 4000 approx.) and in the higher rpm range, there is no difference or I couldn't make out any differences between the different settings. Just my observations.

So the fuelx mainly works in the closed loop part which is less than 6000 RPM approx. Hence its effect will be mainly felt in the lower rev range.

Beyond 5000 kms, the oil becomes black and thin.

KTMs run on fully synthetic engine oil and it can safely stay for 7500 KMS. Correct me, If I'm wrong.

Any increase in FE after using XP95?

The Duke 250 manual mentions a service duration of every 3 months/7500 KMS.

My Duke 250 runs only 500 KMS(or less) every month. So it would be an utmost waste of time and money if I service it every 3 months, right?

Even though manual says 7500kms, people and mechanics recommend changing it every 5000-6000kms/6 months

I did 2 trips recently. First one from Chennai to Kanyakumari and used normal fuel exclusively. It returned a fuel efficiency of ~35-36kmpl when ridden at 85kmph and ~32kmpl when ridden at 95-100kmph. Then I switched to XP95 for my 2nd trip which was from Chennai to Thanjavur and I maintained 95-100kmph throughout and it returned 34kmpl.

So, I'd say the fuel efficiency is negligible but I feel a noticeable difference in low end performance where there's less knocking when using XP95.
I was able to keep up higher gears for much longer in city without having to downshift often

In my BS4 Duke 250, I've never experienced any engine knocking for the 15K KMS. The low-end torque is slightly less when compared to SOHC engines and it's quite natural.

Can you explain more about the engine knocking?

I did not notice much difference in fuel efficiency. But there is a stark difference in smoothness across all the rev range.

The 3 months service interval is too short. Can you check the manual in the KTM app also to confirm?

Previously when using shell normal in city riding conditions, I had to downshift to 2nd when under 24kmph and to 4th under 46kmph, if not, you can feel the engine struggle and if speeds are too low, there's knocking and shaking(eg. when moving from ~20kmph in 3rd) but while using xp95, I can maintain upto ~21kmph in 3rd or ~43kmph in 5th before downshifting

Even if it doesn't accelerate much due to the lack of torque in lower rpms, the engine feels and is visibly less stressful(no knocking, shaking/heavy vibes) when using xp95 compared to normal 91octane at ~2500-3000rpm

The link is from the official KTM app, but the service guys recommends a 6 months/7.5K service

The bike was leaking oil around the 2200kms mark. Took it to KTM svc yesterday and got the front sprocket oil seal changed. The right hand guard had to be changed since it had broken during a fall, and they had a matte black one in stock which I got installed (the left one is gloss black). Also checked the air filter which was completely clogged and got the throttle body cleaned, post which a new software update was done. I’m getting anything between 17-25 kmpl per tankful depending on how I ride. Adding some pictures:

Matte on the right, gloss on the left

The bike is leaking oil for the 3rd time this month. After my previous update which was about the service centre visit on 8th May, I parked the bike for the rest of the week and took it out only on Sunday morning (13th May), which is when I noticed it leaking again, whenever the bike was kept on the side stand.



Took it to the service centre immediately and the following part was changed, and the oil was topped up. I had to pay the cost of the part, while labour and the cost of the oil were waived off. I would've attached a photo of the bill but I've left it back home in Kolkata.





Post this, I moved to Gurgaon last week and have ridden 500 kms since. Yesterday morning, I noticed oil leaking yet again, from the very same area. Will be taking it to the Sohna Road service centre tomorrow morning and see what the issue is. Oil leaking on a 4 month old, 3000 km run bike isn't a good thing, and while I don't mind the charges to fix it, I greatly value my time and mental peace and absolutely shouldn't have to run to the service centre thrice in a month for the same issue. Hopefully, this gets fixed tomorrow morning, and this time I will insist that whatever is done is done completely free of cost. Of course, if they don't agree then I will pay up to ensure that the bike is fixed, but this is not the ownership experience I had signed up for.

By any chance did you lube your chain recently? This is because if overlubed, the extra oil in the chain that gets splashed in the front sprocket drips via the same area.

If it's not, then it's definitely an issue that KTM has to look into it seriously

From what I can make of the picture, it definitely looks like a little oil leak. This is actually a very common problem on ktm engines. I spent a lot of time fixing oil leaks on my college SAE club’s ktm powered car. I’d suggest removing the exhaust pipe and taking a closer look to spot the source of the leak. Judging by the amount of residue, it might just be a sealing ring that’s damaged. Ensure your mechanic doesn’t over tighten the drain plug as that can damage the ring.
