V-Twin vs Inline 4

you believe them figures? if thats the site i’m thinkign of the also rekon the SVThou has 120BHP…its doesnt!

TDJ…you talking about 1000 IL4’s no?

600’s need to be revved hard to get anywhere…when i rode an 08 R1 i noticed the massive diffrence compared to IL4 600’s…wich feel fluffy and revvy.

but then theres the massive power diffrence too, if an IL4 1000 has xxxBHP its gonna feel fairly torquey cos its got so much power?

out of curiousty what are the torque figures for somethign like a 1098?

Nah, it’s only a paltry 111.2 :wink:

1098:

1098 ('07) 77.5 @ 8150
1098R ('08) 90.3 @ 8000
1098S ('07) 79.4 @ 8000
1098S ('07) 79.4 @ 7900

All are actual measured figures done as part of road tests, not claimed.

paltry? well its wether you can use it all…or not;):smiley:

viggens SV-SZ put out 112…tasty!

loks liek its all about the 1098R!:w00t:

I think a 1098 is a better comparison against a gixxa 1000;)

This is the point…for a V2 to get as much power, and more importantly, torque, as an IL4, it needs the extra capacity of around 200cc. Thats why in Superbike class, the IL4s are 1000cc, whilst the V2s are 1200cc. :stuck_out_tongue:

This article is quite good at explaining torque and horsepower relationship (although aimed at cruisers http://www.vmaxoutlaw.com/tech/torque_hp.htm)

Horsepower = torque x revs therefore if you have two bikes with equal torque but one can rev to twice the other, it will produce more horsepower and therefore accelerate faster.

Thats why high revving 600’s can produce the high horsepower figures gaining in excess of 100bhp.
Its ability to do “work” is lower though, so shove a heavy bloke on pillion and the bikes performance will be really shoddy in comparisson to a bigger but lower bhp engine which wont feel the effect so much.

Ducati 1198S

170bhp @ 9750rpm

131Nm @ 8000rpm

Aprilia RSV4 Factory

180bhp @ 12500rpm

115Nm @ 10000rpm

BMW S1000RR

193bhp @ 13000rpm

112Nm @ 9750rpm

Suzuki GSXR1000-K9

180bhp @ 12000rpm

116Nm @ 10000rpm

You pay your money and take your choice.

Very true.

I think the important thing to remember is they are just numbers. On the road the gearing of the bike also has a huge influence and especially key to the use of the bike.

A big twin with low gearing will be great round town, lots of power pretty much instantly in low revs.
Want to go long distance on varied roads and I’d go for a nice four cylinder, smoother with power in the higher rev range where you’ll be more of the time on faster roads.

I’ve yet to try a triple, I mean to get around to it one day, but I have heard they are the best of both worlds.
