Security will be higher in the one which is difficult to cut.
It would depend upon -
1. Material
2. Alarm System
3. Thickness of pin
4. Position of pin (should not be locked where its very easy to break/ cut the lock!)
So circumferential one has to be with a smaller pin < 6mm but difficult to cut because of low clearance. On the other hand, a circumferential one can have a larger pin - like 14-15 mm but it has more clearance to adjust & cut.
My advice, Buy a XENA for front & a Local one for rear!

I have noticed the fuel sensor doing funny things aswell!

It suddenly starts Trip F and then return to normal and the fuel shows one bar! At other times i have noticed that the fuel sensor keeps fluctuating between 2 bars and 3 bars it is not very stable, the senspr probably changes readings as the petrol inside shifts to the front and back during braking and accelerating respectively. Isn't it supposed to be constant? should it be understood as a defect? Anybody who has highlighted the issue to ASC?

How much has it been costing for a normal service of the duke I am assuming even for the first free service we will have to pay for the consumables right? What is the cost of the oil? filter? coolant? lube?? etc.,?

Harsha - Assassin explained it quite well. Hope that helped you.

MEZZO ????? ?? ???! - this is the one I am getting (from Korea of course)

So if you buy the XX14 - You can lock the front disc through the petal groove but not the rear. If you get 6 then you can lock both front and rear. 2 locks - imagine the cacaphony!

XX I guess is the latest in their series. The XX series locks are are quite stout compared to XZZ and XN series.

sharingan my friend has XX series

AsheshAmbasta another friend has XN or XZZ - much slimmer than XX.

1) My coolant has always been slightly above the min mark - thankfully no overheating problems in traffic, no coolant spilling out.
2) I have the same noise coming from the chain hitting something (probably around the the gear shift lever area) It makes a noise only while i am decelerating in gears 6,5,4. I go to service station, they add soft rubber piece, tighten chain and it goes away ... only for the noise to restart after a few kms later.

Do let us know if you get your chain noise sorted out.

@Assassin : Thanks for the superb explanation I'm quite clear now on how this stuff works.

I'd probably go for a XENA XX6 for the front and a local one for the rear, as you suggested.

@Shubz : Appreciate your feedback as well.

What oil is recommended for running in? I do not want to wait for the first service which is 1000kms away, changing the oil and oil filter sooner would be a smart thing to get the metal particles out of the crank case. I am aware that semi or fully synthetic oils needs to be avoided at all costs. Guys please throw some light on this.

I peeped into the tank, but can't see the float! But hey, the issue has been magically solved yet again

I live in HSR layout.
And here goes the details for the benefit of Bengaluru Dukers!

"Hi Creative" sticker shop near Sachin's Autoshop, Koramangala. Ask for Hafees and mention about his first Duke customer And btw, price is 200 bucks vonly
His number: 9916909422 (I have not tried the number myself, this was taken from his assistant)

And try to get the work done by himself rather than his assistants. He does it best there.

Are you planning to replace the oil twice during run-in then? Whichever brand you use, stick to the proper ratings.

Rishi - Can you please tell us from where you got this info that semi-synthetic or FS oils are to be avoided?

Many Duke owners are shifting to semi or FS on first service here.

I think he meant to say synthetic/semi synthetic is to be avoided during run in. Even I have heard of this philosophy. May be someone can clarify if that's a valid point and if there are reasons behind it.

Even that is incorrect I guess. Hyosung 650 comes with FS from the factory.

Good God.. only 200 bucks !! it looks really neat... has the logo too.. The original powerparts rim stripes are around Rs.1300.
koramangala is pretty close to my place... could get this done over the weekend.

Issue rectified

Yesterday I got my duke back and now I have ridden it around 80km and its running fine. I understand that duke is a new product and some problems might crop up in first few lot but appreciate how bajaj handled the issue.

Definitely will. It really is good to live on the ground floor :-D But I'll really have to make up a good excuse to get my bike "inside my house" wow that would feel soooooo awesome :-D

Thats the thing I can't find it here in India. I have to order it from the UK and with that insane shipping cost...I'm using the local Disc Brake Locks and my 3 Pet Stray Dogs that Sleep next to my bike :-D ...Always barking at anyone who passes by :-D ...I just Love them!!!

I guess you are following what you've read about the motoman method of running in...that holds true only for a few super sport bikes, Our bikes don't run-in the same way, hope you haven't been red lining the engine too much.

Yes, I am planning to change the oil more than once during the first 1000 kms, not sure if the SVC guys would encourage this.

Its absolutely okay to switch to FS or semi during the first service, I was talking about the first 1000 kms. Switching to FS oil later is more preferable than sooner. (Source of the info: 80% of reading and 20% of logical reasoning) Courtesy motoman and few other sites.

Yes, thats exactly what I meant. Synthetic oil is too slippery that it actually "arrests" the break in process before the rings can seal completely. Switching to synthetic oil too soon will lead to improper sealing of rings no matter how hard its been ridden.

I wouldn't know what oil the Hyosung 650 comes from the factory, why would Hyosung make such a blunder regarding the oil. I have heard that most of the bikes are run in by the manufacturer itself, so the bikes can be raced in the track right from the factory. Not sure how far its true.

Red lining is not recommended on any new bike for that matter, the RPMs needs to be increased progressively, by varying speeds and changing gears. All the bikes are similar, just the technology and the material used are different. Just listen to the bike and make sure You don't overwork it.

Disclaimer: I am a newbie here, so bear with me if I have provided any incorrect info. You guys are more knowlegeable and experienced so I am always open to Your feedback.
