What RPM at 100km/h?

[Brownie586]

Hey everyone,

Just wondering what RPM everyone's gen 1's do at 100km/h. I'm trying to figure out if my bike has different sprockets.

Currently mine sits on about 3250rpm in 6th doing 100.

Cheers.

About the same...if you are a bigger person then it will be different

[Brownie586]

If i'm looking to bring that down a bit for fuel economy, can anyone recommend a chain and sprocket combo??

Also do the electronic speedo correctors work??

Never used a speedo healer, but presumably they work. Here are some Gen 1 figures; they'll give you an idea of the effects of gearing changes, but you'll need to convert them to kmh:

....... 1st 2nd 3rd 4th 5th 6th

16/39 77 104 132 157 178 194
16/40 75 101 129 153 173 189
16/41 73 99 126 150 169 184
16/42 72 97 123 146 165 180
16/43 70 95 120 143 161 176

17/39 82 111 141 167 189 206
17/40 80 108 137 163 184 201
17/41 78 105 134 159 180 196
17/42 76 103 131 155 176 191
17/43 74 100 128 152 171 187

18/39 87 117 149 177 200 218
18/40 85 114 145 173 195 212
18/41 83 112 142 168 190 207
18/42 81 109 138 164 186 202
18/43 79 106 135 161 182 198

19/39 92 124 157 187 211 230
19/40 89 121 153 182 206 224
19/41 87 118 150 178 201 219
19/42 85 115 146 173 196 214
19/43 83 112 143 170 192 209

I don't think you'll get any significant fuel saving by playing with gearing for that speed.

For economy my gen 1s did about 20-23klm per litre is I was cruising at just below 100 constantly. Standard setup just lay off the throttle lol

Hiya,

Speedo healers do work. I've used em on a few different bikes so far. All set n forget sort of a deal.

I reckon changing sprockets for better mileage is false economy, better throttle control gives better mileage. 383km@18.5lt Gen 1, 398km@19.7lt Gen 2, both std gearing.

I bought a Throttlemeister for long trips....... if for nothing else than to give my right hand a break!!

Enjoy the bike

Here you go Brownie,
You can play with gear combos to your hearts content.

Changing the sprockets will not effect what the speedo reads compared to the revs, as the speedo drive runs off the front spocket. Comparing your tacho to speedo wont tell you if the sprockets are different. Your gen1 should have a 17 tooth front and 40 tooth rear. Count them is the only way to tell if it's stock.

I used to think the busa was hard on fuel until I went out and bought a 6 litre commodore
Now I look at the busa in a whole different way

It's all about perspective!!

Yep .. I guess if I compared the commodore to a top fuel dragster then it would be pretty good too. The top fuel dragster that is ..
These commodores seriously have a drinking problem.
Sorry for the ..

Try owning a V8 Land Rover discovery and it would make a top fuel dragster look economical

Compared to my old VJ Valiant with a warm 265, the Busa is like a friggin Prius

That chappie that ran outta juice at Bathurst could have done with a Prius!

My original 99 with stock engine and Yoshi cans works at 3000 rpm @ 110 kmh.

How does that 6 litre compare to a 4 litre G6E Turbo ? in your opinion?
