what i'm trying to say is don't get hung up about being overtake on the straights and relish in the fact you are keeping up in the twisty bits. ragging the titzz out a small bike with crap suspension and mediocre brakes takes more skill than twisting the throttle on a super sport to blat past people.

Time for a re run of Blue sv and his utubes of Silverstone methinks.Anyone got the links for any of those?

Screwing more power out of an SV (or a ER-6 for that matter) is not cheap.

New Weiseco pistons and carillio rods are about £600 just to buy. Set of lumpy cams about £600 again, full system exhaust £800- £1000
Being an injected bike, you will need a Power Commander and a load of dyno time about another £600
That will gain you about 10 BHP

There is a reason a JHS SV650 costs over £21k to buy and a KMR ER-6 about £20k. JHS are getting about 90 brake out the motor and KMR about 105 brake, and the engines are relaible but need some proper TLC to keep perfect

Personally I'd say enjoy the SV for what it is, a capable bike with 70-ish HP. When someone comes past on a ZX10R good on 'em, when you go past them, there's no arguing about whether it was because their bike was better!

Weight can be saved a few places. For track days you could consider simply unbolting the whole front plastics / headlight etc just leaving the instruments. Less to damage in an off, and I promise you the aerodynamics weren't helping.

Ha ha, like my pal who I went to Cadwell with who was on a GSXR1000 with pretty much brand new Supercorsas on. Scary!

I leave the full fairings on for trackdays but take off indicators, mirrors, number plate etc. Seems too much of a faff taking the headlight and nosecone etc off, especially with no garage and next to no mechanical skills!

Got a stainless Scorpion on. Could possibly go for something lighter though.
The pillion pegs havent been on for years.
Rider could definitely lose a few pounds! He's working on that all the time.

How about selling the SV and getting an Aprilia Tuono. You can get an 03 model for not many £££ these days. And they are oodles of fun plus they still have the V twin grunt!

But he'll be quicker around the track on his SV650...

you won't find a SV that does more than 140mph IMHO

you wont find a sv650 that does a 140mph!,correct,try nearer 125mph,
if you want more speed as others have said buy a faster bike,it will be cheaper in the long term,plenty of fast bikes out there for 1.5k

The best of the best supertwin sv's will just crack the 140mph but yes, major surgery required.

(Ivan Lintin's bike did 141 mph thru the sulby speed trap)

Higher top speed doesn't always equal lower lap times.
Club racers in the U.S. ride up a class with their SV650s (Lightweight twins) and they often win the Heavyweight twins races. They always have finishers in the top 5.
My SV650 will reach an indicated 135 mph with just a pipe and some re-jetting.
I know club racers who were making 95 rwhp with their SV650s 13 years ago. I'd guess they easily went an actual 140 mph.
