Have shown it to the Enfield service station. They said they have done some "tuning" and it it would be okay now. But not so.

Not that I speed, but it's embarrassing, to say the least that a 500cc bike should struggle to go about 80 Kmph! On highways, sometimes this speed-limitation isn't something one would want.

Anyone else facing the same issue? Any pointers of how this issue could be resolved?
Anurag, the C5 should easily cross 80kmph and should go strong till 90-100. Please check if the airfilter is clogged or not. Did you notice any drop in the oil level of the bike?

That would be helpful. Sent you a PM.

Yes, all the checks (air filter, oil, EFI tuning (as per RE service) have been done. In fact, I explained this issue to RE in detail and was the No. issue to be resolved the job card. They said that they cannot do a road test but as per their adjustments and checking on the dynamometer it is okay. But clearly it isn't the case. I am now going to try replacing the upswept exhaust with the original one that came with the bike, and see if that helps.

sgmitr13 - the PM didn't go through. It needs a BHPian status that I don't have yet. I stay in S. B'lore. If you can PM me, I'll respond.

I too have the upswept exhaust installed and feel it isn't the issue restricting the bull below 80kmph. Please ride another 500 bull and feel the difference yourself and then take the issue with RE guys.

Yes. It has been the case since Day 1. Do you know of any expert mechanic in Bangalore?


@ sgmitr13 - I have an upswept silencer. I too had thought that this could have been the issue. However, the RE Service Centre said that it shouldn't affect the speed. Somehow I've started to lose confidence in the RE service guys, especially for any non-trivial issues.
where are located in bangalore? If around koramangala area, you could visit "art of motorcycles" ( behind bosch, close to dairy circle) and show them your bike for a general diagnosis.
PS they will be away for the Rider-mania this friday onwards for a few days!!

I'm at JP Ngr. but can go anywhere in B'lore where this issue can be resolved.

Is this the correct page & address for AoM? https://www.facebook.com/artofmotorcycling

Thx. for the ref.

Try to get these checked:-
1. Condition of clutch plates
2. Cylinder compression pressure
3. Fuel pump
4. Condition of Inlet and exhaust valves

My dad has an old parallel twin 175cc Honda which i maintain myself. This had a similar problem. After attending point no.2 by replacing piston rings and lapping the valves i was able to increase the performance. But then this is a 45 year old bike and the rings and liners had worn out. This should not happen in a bike thats not so old.
As someone has correctly said on this forum ride another bull to compare and make a note of the difference in pick up and fuel efficiency.

As the others have said, your C5 should easily do well over 100 kmph without working up a sweat.

One thing that hasn't been mentioned is the possibility of a dragging brake.
A dragging brake can keep the motorcycle from achieving reasonable speeds and if that is the problem, a routine servicing might miss it.
I know of several cases where the front disk brake fails to fully release and others where a mechanic(?) had adjusted the rear brake to the point of constantly dragging.
It might be a good idea to put the motorcycle on its center stand and then, with the transmission in neutral, try rotating the rear tyre by hand. It should turn freely.

Without removing the bike from the center stand, use a automotive screw jack or something similar to jack up the front of the motorcycle. This jack can be placed under the front motor mount to accomplish this.

With the front tyre off of the ground, rotate the wheel by hand. Again, it should turn freely.

If the brakes are fine, the air filter is clean and the tyres have the correct air pressure in them, about the only thing left is a problem with the ignition timing or the fuel injection system.

As your mechanic said these were fine, contact Royal Enfield and arrange to have one of its technical advisers ride your motorcycle. After he is not able to get it above 80 I'm sure he will become interested enough to resolve the problem.

I have a C5 - Oct 2011. Done merely 5500 Kms. However, after 1700, I could reach 130 kmph and I can still do that speed whenever I take it out - though once in a month. The only change from stock is NGK plugs.

I have been servicing at Teknik HSR lately. However I think you need a specialist to check. 80 kmph is a cause for worry.

Thanks argchoff, ArizonaJim & nareshtra for the suggestions.

It does certainly confirm that my C5 has issues. I'll try out the suggestion and will try riding one or two C5s to compare. Will visit a RE specialist as well. Let's see what they have to say. Will post an update soon.

Does make a difference. Not too dramatic though on performance but eliminates misfiring etc. completely,

These also come in sets for RE - Both Primary and Secondary in a box - I bought from Teknik Motors in Bangalore 2 years back. Saw the same being advertized on DSG site earlier as a set for 1100 Rs. However, could not find it today. Will look for the box at home and publish the specs if I find.

I have some official work at manali next week.Was thinking of renting a desert storm from chandigarh and do the distance by road.Apart from the riding gear, what about the ride itself? Is it going to very difficult? I haven't ridden a two wheeler over snow or iced road before.
