Re: Not revving past 11,500rpm in 6th
 

Ahhhh now all my riding is for fun


The key hong, is smooth and progressive, not scrappy and aggressive.
Now I proclaim my riding is not too cracky, however people who are far more proficient say in honesty, I am on the smooth and progressive list.

Not too sure about that myself, but nowts blown up yet, and I ain't fallen off :)


Mood of the day certainly has a lot to do with it in my case. On Saturday bringing the soho crew back to base I was apparently getting a fair lick on, to me I was just bimbling! ...and thats in the rain. Rain or sun, I ride exactly the same...I don't think so, others do!

Higher rpm does not necessarily translate to higher speeds ;) You will be amazed how much fun, and sometimes faster, bikes can be when ridden at lower rpm with more power and torque ;)

Yes I know Lou, I was just...nevermind.

Max, I was more referring to if people rode around all the time concerned with optimum fuel consumption and MPG.

Re: Not revving past 11,500rpm in 6th
 

Aside from the obvious reasons for being cautious doing this there was the original question:

why wil the bike not hit 12k in top?

My bike will never manage that, it would stop short of the red line because it's on standard gearing. There comes a point where the motor cannot produce enough power to overcome the increased friction as the air resistance builds. This would occur when the bike is pushing hard but the revs simply won't rise any further.

Alternatively if your bike may be hitting the limiter because that happens at a lower road speed than with standard gearing, in which case the bike can't go any faster due to the rev limiter. This will be characterised by reving then cutting, then reving, and should be fairly obvious, the only way to solve this would be to gear UP, but in all probability you won't get any more speed doing this as the motor may not have much more to give.

Why would the bike have managed this before but not now? Either:
1) It is making less power
2) There is more resistance

Point 1 could be down to simply needing a service, the fueling not being quite right, the air filter being less clean or the motor just not running as well.
Point 2 could be tyre pressures, chain condition, or quite likely the way you are sitting on the bike or clothing you're wearing. Air resistance is a pretty massive force at this point and even small changes in body position and clothing can make a fairly big difference.

Personally as I said I wouldn't worry about it at all, but that's me and I'm not going to get involved in the arguments about what's appropriate and when.

Edit: I am one of those mpg obsessed smooth riding souls, and keep up with most, but everyone rides the way they want to, and no 2 people are quite the same anyway :)

Jambo, my hero! That is spot on the type of answer I was looking for. Not that I dont appreciate the rest, its been quite educational ;)

Now trying to remember back to when it did hit 12k, I'm fairly sure I had the topbox OFF. That is obviously a big drag item.

I've hit the limiter in lower gears before and its quite a harsh feeling compared to what I'm feeling in top. Its almost like a soft "feathering" or hesitation.

Re: Not revving past 11,500rpm in 6th
 

I wasn't referring to optimum fuel consumption because that would be a at a lot lower rpm and would depend more on the speed than actual rpm.

You still get the benefit of some extra power even though the torque starts to decrease. But only until about 9k where torque drops so low that the extra rpm can not sustain the power. At this point is better to upshift.

I personally ride progressively in the 7k zone with shifts around 8.5k. Most of the time though, I don't don't shift over 7k.

Re: Not revving past 11,500rpm in 6th
 

How does gearing down a tooth affect this? Does it shift the optimum range up or down?

Re: Not revving past 11,500rpm in 6th
 

Errrr yeah, I'd say that's worth a mile an hour or 2 :smt104 :mrgreen:

Re: Not revving past 11,500rpm in 6th
 

I cant be 100%, but probably not one of my brightest moments.

I assumed actually that the extra drag of the top box (or anything else) would affect the bike in that it wouldnt be able to reach the limiter, not in the sense that the limiter cut in point would come down slightly.

If you see what I mean? Im **** at explaining what I mean.

Re: Not revving past 11,500rpm in 6th
 

Heres a thought as far as revving the knackers off your SV is concerned

I was told by a very valuable source to stop riding the VRap like an SV, and learn to ride the engine and torque it has to give.

Now then....revving the SV to such a max etc....

Do you think you are using it like a 125 or an SV?

Humour me.
