is this HP figure right ?

i want to buy an sp1 now lol,
there is one i have called about that has arrow bolt on cans , power commander with a custom tune and the owner says it produced 116 hp at the rear, i thought it might be a little higher than that, what would be average with those mods do u think?

also as a first time buyer of this model, what questions should i be asking the seller?
there is also a bone stock one for sale but he wants the same money for it, i wonder if it makes sense to buy a modded one or a stock one and mod it how i want ??


cheers for the help

That hp is about right for bone stock.

Do a search as there are quite a few threads out there dealing with your questions on what to ask/look for.

Every dyno can produce different HP values, one dyno will get you 116hp, yet take it down the road to another dyno and you can get 125hp.Dyno jet dyno's are famous for this, the operator can tweek the values to read up to 20% more power, you have to tell the operator you want a true HP reading.

If you are worried about horsepower then the RC is not the bike for you...

no, not worried about hp so much, but i thought i read somewhere a standard one produces around 120 at the rear so i assumed one with cans , pc and a custom tune would have a few more ponies,

like they say, dyno figures can vary a lot too.

Every dyno read differently due to variations in calibration. What you need to see are the before & after dyno charts. The difference shows you the overall gain.

If the bike had 104rwhp before the tune and now has 116 then great if it had 121 before the tune and now has 116 well... you get the point I hope

what you should be looking into is the torque because that translate directly in pulling/pushing power which is the measure of acceleration. Usually in general terms, BHP equates to top speed but Torque equates to how much the bike will pull on your arms as you fly past the car you are overtaking!!
