Hi fellow bikers,

Even I feel that the refinement is an issue with CBZ Xtreme(mine is a latest Oct 2011 version). I consulted my mechanic which he told that it is an issue with CBZ Xtreme. When I complained about the same to SVC guys each time during the free services, they would tighten the engine mounting bolts which did no good and the issue is still existing. They admitted that it is the characteristic of this bike and no other HH bikes have this vibration problem.

The harshness of CBZ Xtreme is such that the we feel like the engine is crying out of breath once we cross 60 KMPH in the top gear. The bike feels good below 50 KMPH - 55 KMPH but becomes harsh when crosses 60 KMPH. I really doubt how the same engine (slightly de-tuned) when put in Unicorn behave more refined and in a flawless manner. I would rate pulsars to be better than CBZ Xtreme in this aspect.

Now I have crossed 12K KMS, I stopped complaining SVC guys about the engine harshness and I am trying to get myselves used to those vibrations which I find very hard even now.

My normal cruising speed is between 60 - 75 KMPH, which is Xtreme's peak vibrating range and is irritating me each time I ride this bike. I used to love the breezy ride in my previous bike R15 in 6th gear in that speed range which I had for 3.5 years and crossed 50K Kms on the odo. I had never felt any such vibrations in R15. But lately R15 started giving electrical problems which could not be resolved by Yamaha SVC's even after shelling around 15K........this made me to sell off that bike (in an angry mood against Yamaha ) and I decided to not to buy Yamaha again (which I am regretting now that I should have waited a lil more to solve that problem )and came to HH-CBZ which I thought would be a good option with less maintenance. But I agree that the maintenance is a lot cheaper when compared to my previous bike which is the only reason I am consoling my selves.

After shelling 74 K for this bike, it is a bad idea to sell this bike now and I have decided to get used to the engine harshness till at least for two years after which I would look for a better option.

And to all guys who are planning to buy this bike, try to take the test ride which I was refused by the SVC when I bought last year (HH Nagappa Auto , Chennai). I think they are giving test rides for all the bikes now and if they don't give, tell them that u won't buy. After all its our hard earned money and don't get fooled by the brand name. Test ride at all the speed ranges and check whether it suits your riding style and if it suits you can very well buy. The mileage is between 38 - 45 KMPL depending upon your riding style.

Hope it throws some light on the negative side of this bike. For those whom the vibrations do not matter much I think this is a good VFM bike.

Hi All. Had a worst experience with my Xtreme. My bike stopped in between. Had to drag it 5 kms to reach home. Night time had no mechanics around and heavy rains. Couldnt park on the highway. Reason was the water had penetrated in the tank. And start plug was gone. Friends please put a tank cover. And keep a spare start plug with you. Its been around 8 months and I have just run 1800kms. Didnt expect this from a HH bike.

Every problem has a solution. In your case get hold of a good mechanic and try to troubleshoot the problem. Without finding the problem you cannot say a bike is bad or what.

If your tank has water then find the reason for water entry. Simply saying i didn't expect this from hero honda is not a solution. In every bike water enters the tank.

Now, I've crossed more than 1500 kms. Present fuel efficiency is 45-50 kmpl with speeds from 50-90 kmph.

Is this thread dead or what?? Wake up all of your Hunk and Extreme owners. Time to get contributing to the thread for the benefit of all of us. Time to gradually build this thread into a strong helpline rather than just posting occasional 'ride reports'. Seeking some inspiration from the Splendour thread. Fabulous thread that one - deepest technical insight into their bikes - time to learn something and contribute the same to this thread.



Dude are u sure that you've checked your mileage properly at speeds of 90kmph?? I am dead sure that 50kmpl at those speeds is impossible. Really!

Might be that you had touched 90kmph for 1-2 secs and got back to the average speeds of 45-55 kmph. It is possible then, otherwise not. I have done some short rides on my Hunk (700kms once and 300kms ) at speeds continuously over 80kmph (I averaged 85kmph) and the mileage was abysmal. Got around ~35 max.

My Splendor's original chain sprocket was replaced around 85K! Then I replaced with a complete new chain sprocket set and it lasted 25k only
But don't remember the model, either it was Hero genuine / Rolon.

Do you mind me contributing to this thread. If you remember then i am the same who contribute technical knowledge in splendor thread. I also own a extreme and i will post technical know how, alternate and better parts and how to get good mileage.
Regarding mileage i get a mileage of 55-58 kpl in city on my extreme and 62-65 kpl in highway. I usually ride in 5500-6000 rpm on my extreme which translates to 75-80 kph on highways. My work place is 80 km and i ride up and down a total of 160 km a day. I alternate between my joy and extreme each other day. The fact is i accelerate gradually and then brake gently on highways. So the mileage is high. Since the maximum torque is at 6500 rpm the mileage will also be high at that rpm.
At the end anybody having any problem then please post here i will give all the knowledge that is required and do not worry slowly i will turn this into technical thread like splendor.

Are you sure abt the milage b/w 75~80?
For me
I used to go 50~55, milage 50+
45~50 then maileage ~55
once I got ~60 while on speed 45~50

But once I rode 40kms on high way @ 75~80kmph my mileage dropped to ~28

Yes i am sure because every other day i take the extreme to work and this requires 60 km of highway.
My joy also i use at 70-80 kph and it returns 72 kpl.
The fact is that the air screw setting has to be correct. Neither a rich mixture will give more power nor a lean mix will give more mileage. When the air screw is set correct then only your bike will give power and mileage.
My mechanic admits that 99% of mechanic do not know how to tune bikes. Either my mechanic or i tune my all bikes. I never let any one touch the carburettor.
My mechanic tunes the carburettor so good that it gives more mileage than factory tune and also the bike revs more freely than factory tuned bikes.
Some batches of extreme and hunk had valve problems. So they returned bad mileages. My mechanic opens the head and DE- carbonizes it and also polishes the valves. The mileage increases as compression was leaking through valves. Those bike that had leaking valves had very bad mileage.
Another one advice is never use 20W 40 in extreme. When i used 20W 40 in my extreme immediately my mileage decreased to 40-45 and after 300 km when doubting oil i changed to 10W 30 mileage again increased to 55-60 kpl.
SO all extreme/ hunk owners just use good quality 10w 30 oil or 10W 40 oil.
You mileage will increase.
