When should i be changing gear

OK Ive searched but not much info .You don't learn it on CBT an every bike is different .Not meaning to sound like a fool but i find my 1992 NS125R foooking fast .

Ive got it up to 70-75 an it feels like it will just keep going (an im 18 stone "ish")

Problem I'm finding at 6k the power band kicks in 1st gear an the bike starts to lift i feel the front end rising .An when i hit 8 1/2k i change gear an it keeps the revs at about 7k with the power band still going if i go 3rd 4th while keeping it at 7k the power band just stays on an the bike fly's .

Your probably thinking an yea the problem .

Problem is the bike is to bloody fast on short roads I'm pretty sure i can hit 50 in a few seconds .

The last owner said Cu's of my size i wanna keep it at about 8000 before changing but this is when the power band is fully kicking in so I'm just going faster an faster .

normally if not going far i don't let it into the power band 1st gear before i hear that loud Rmphhhh i change gear to 2nd so it keeps the noise down an a steady slower speed .Then the same thru most gears as well most roads are 40 50 an by the time i get to 4th im doing that easy.

i think its fully derestricted so i don't know top speed what does the NS125R do cus i got slight feeling ill hit 100 .

I'm not shitting you an any one is welcome to come have a ride .Its actually scary for 125 i was no way expecting this kind of power from it .

on a long road i find i can get it at steady 50-60 in 5th 6th gear but it wont go faster just slugs along an if i want it to speed up i drop it a gear open it up an watch it go to 9000k then go up gear an keep raising speed .

So when "should i change gear" / is there any problems with changing at low revs obviously lower speed but this is fine .
Whats the top speed of a derestricted 92 model NS125R .
If its in 5th doing 75 an going thru the power band up to 8 9k an still producing a shitload of power this good ?

Ive never let it go to 10 11k the redline as red normaly means bad .
Is there any problems with letting t he revs go that high .What gear should i let it go into the red .Im guessing to get top speed i hit the powerband at 6k in 1st then follow thru the gears keeping the revs high then around 5th let it go to 10000 an change to 6th an then just let it hit red ?

I got no clue so please inform me thanks for your time an help

P.s this isnt a i want more power my bikes to slow thread actualy the oposite fo rthe moment im happy with going slow but seems my bike dont like slow

First things first, The bike only goes as fast as you make it go. Theres no need to blast through the gears- throttle control is the best way to keep a steady speed.

I reccomend "Short shifting" as the best way to keep a decent speed and keep in a usable rev range, You've probably already done it numerous times but havent thought about it.

You dont have to reach the top end of a gear before shifting, you can shift up at any time during the gear(obviously not too early or at slow speed as this will cause a stall).

I find this the best way to keep a sensible speed around town without it revving at a stupid rate, Although its not very often I short shift Laughing

.

Also dont worry about redlining the engine, As a sportsbike Honda would of built the engine in mind of being revved hard a lot so you could redline it in most gears and anyway a good blast on the throttle everynow and then only keeps the engine sweet Very Happy

thanks brooky spose i answered the question myself then .Change gears when i want to change .

I just wanst sure of any damage as when i go 6-7k in 1st gear the bike roars like monster an the power kicks in .Ive only had the bike 1 week an never owned 1 like it befor so its more damage im worried about .

Well plus the fact the speed its got .Its like they say dont be mouthy if you cant back it up .For the bike it can well backup the noise with power .

I live near an old unused airport lydd so i spose i can go find a long bit of track an get a feel for the speed .

So redlining in 4th 5th 6th will cause no trouble .An i should open it right up now an then to clear the engines chest lol Thumbs Up

Glad I could help mate. The reason you say the engine roars at around 7k is probably because its enetering the power band and the revs will pick up much faster than through the lower half of the gear.

Im not familiar with what you bike redlines at but it will be fine to redline the engine in those gears you stated, Obviously dont do it every time you accelerate just when you need to as theres no point in putting extra strain on the engine, chain and sprockets unessecarily.

Basically its upto you how hard you push the engine but I wouldnt encourage ragging it all the time, The majority yes Wink

but give it time to rest to.

Just be sensible and you and the bike will be fine, You will soon learn how hard you can push the engine and start to feel more comfortable in you riding.

Take it easy, and enjoy!! Thumbs Up

Thanks again m8 much appreciated .Tbh as ive said i really dont wanna kill the engine neither do i fancy going round ringroads as fast as possible .If you have ever been to ashford you will understand the whole area is ring roads 1 way with 3-4 lanes so top safe speed is like 20 30 roundabouts an lights every where .

main concern was told to keep it in the high revs 8k as im pretty heavy but i personaly feel its unneeded to keep the bike in the powerband thru everygear .I just cant stop in time for stuff .

Ill keep being a slug around town an leave the high speeds for dual carageways an country sides .

1 last thing do you think bcus of me being 18 stone on the back is why it causes the bike to lift when hitting the powerband im pretty sure i could get it right up (altho ide never want to )

If its anything like my RS then it will lift no matter what u do ( apart from going slow of course... )

Basicly the powerband kicks in at a certain ammount of revs, on mine its around 7k rpm, sounds like the same on urs. Its just the sudden bit of power you recieve and the type of suspension bikes use that makes it lift, nothing to worrie about ( of course u dont want to be pulling wheelies everywhere and falling off... )

I rember the first week I got my RS125, I really did think I would give any 1000cc a race for its money up to 60mph! Untill I actually sat behind one at the lights and he gunned it.... Still I beat an M3 off the lights and he was gunning it so im happy with it Very Happy

I used to have an NS125R with a micron expansion chamber. It was exactly as you describe. The top speed was 90mph (indicated) but it got into a scary weave at around 80mph.

But it did wheelie when coming into the powerband in first and second... Twisted Evil

In answer to your original question... change gear when you feel comfortable!

meh, let it run into the red every now and then. My bike has a rev limiter at 11500RPM so i don't have to worry too much about lunching it. Extend the change point to 10,000 and see how it feels, the later you change, the earlier you'll get into the powerband in the next gear.

lil red thats my point m8 the powerband scares the shiat out of me lol .

Have you ever seen a 18 stone dude on a 125 at close 100 mph its funny yes bloody scary to.

ive got a felling the the bike is fully derestricted .Its not got a standard can its a huge fat thing the whole way down .kickstart did mention the name of it he said some bloke designed it i think then sold it .

i know the bike had full rebuild so im guessing its derestricted .I dont know much about bikes but im thinking it has larger jets (can you get carbon fibire types) i think thats what was added
