Ideal Shift Points

Interesting.

This is different than what I read before, which called for earlier shifting than this article suggests is optimal.

Thoughts?

I read the article, and apart from explaining it in the most confusing way possible, i think its probably right. The SVs peak power is fairly near the redline anyway. Just bear in mind that hitting the rev limiter is not a good idea

The thing that caught my eye about this article was just earlier that day I was telling my friend... blah blah blah "I am shifting too late..." -- based on some 'best shift points' article I saw somewhere and what I noticed when checking the tach while riding earlier that day.

I had heard that I should be shifting something to the effect of 10.2Kish in 1st, 10Kish in 2nd, 9850ish in 3rd... etc... I dunno. Something like that...

Then I see the aformentioned link when looking for that same article which basically says redline the first three gears. I was wondering which was correct.

For sure, the latter makes more noise.

That guy is wrong and you were right. I don't know how anyone can look at the tach while riding anyway but the sv runs out of power at about 9500. So there is absolutley no point going beyond this in any gear. The extra couple of thousand to redline is a safety margin and you should always avoid hitting the rev limiter to save engine damage and to accelerate faster

i agree, waiting to redline will do nothing but hit the rev limiter and ruin a good pass.

well whether its rights or not i tend to change gears at about 5k-5 n a half k, from hearing the noise the engine makes when it goes over this in the lower gears, im just frightened to take it up that high incase i do do some damage to the engine.

you should try an inline 4 then... I had a go on a friends ninja and the engine sounded like it was going to tear itself apart above 5k, with a redline of about 13ooo!!!

Rev it up boyo, they're designed to handle it, just avoid the redline unless you like sounding like a t**T!!!

Give your engine some stick. If you don't it'll never be properly worn in and won't function to the specifications that it was designed for. Providing it's fully warm, occasionally rev it right up to 10,500 rpm. This will do it no harm at all.

As for peak power, somehwere between 9-9,500 revs for a standard SV, depending upon exhaust and fueling. Peak torque of course comes a lot lower.

Short shifting will see you generally beat another SV side by side, that is taking every gear to the redline.

I'm not saying it's not fun and doesn't sound glorious though.

I thought the idea of a rev limiter was to limit the revs, thus negating the possibility of over revving the engine

how can shifting gears early help out drag another sv side by side if it produces peak power at around 9.5-10,000revs doesnt it make sense to take it to thats point to go as quick as poss?
