Basic SV650 Track / Race Geometry and Suspension Settings | LWTRacer.com

Some basic suspension settings for your track or race Suzuki SV650.

[@DB-so8zc]

This video is fantastic in. explaining the SV's suspension geometry, shock and front suspension setups. Just picked Gen 2 track bike from a guy in OH (JT) Came with many spares and a tank that you repaired and painted for him Looks great BTW. I just plan on doing track days and at 61 yoa chasing lap times. Your numbers will get me in the ballpark. The bike will be way more capable than me anyway😀 Thank you!

[@jrpark22000]

Simply put, Thank you! Quite a contrast to the complicated nature of fine tuning for each individual but having a starting point puts folks miles ahead.

[@DB-so8zc]

Great info. Just getting in the ballpark is a huge help! TY

Thanks, another great video. Very helpful

Shock length as recommended by Ktech is 341mm, minitwin boys tend to run 337 from experience but that depends on what fairings they’re running etc etc for ground clearance. For people running stock then just do a sag set up and get 35mm then you are in the correct area. As for trail and offset, you can in theory just drop the forks will adjust your trail but you can create stability issues so set up varies on what track and rider, this is probably the most technical way I have heard someone explain a basic job like trail/sag and damping

Fuckin love those Hyperpro Shocks, well worth the money

[@darksoul4721]

Is the steel trellis frame better for sv or this one?

[@mino6466]

I run 510 and 335 on my 2nd Gen. 345 rear was twitchy for me. Bike fell into corners too fast believe it or not and was unstable. More effort to turn but feels planted. Now I am thinking of giving 340mm a try...

[@Torques_moto]

What are those wheels? They look awesome

[@kevinedwards9365]

Sorry for the off topic question. What plastic and subframe is that ?

[@Errol.C-nz]

Ive studied most of your posts everal times.. procrastinating the decision on RS vs SV & the costs differences between them.. we have a LOT of SVs here in NZ & Im wondering what you would think it takes to make the SV competative with the RS.. thinking over bore > 700/750 to bring the current fleet of SVs up to that RS std.. Aprilia has up'd the stacks & its likely itll kill the class here , at least split the class..which would be sad.. its shame yamaha sorta missed the boat with their r7..

[@02TuRD]

What are your thoughts on ball parking rear sag? 25-30mm?

[@slatemytakeaway6400]

Awesome video, Do you have a base setting for a 1st gen on stock 160 tyres please ?? I'm thinking 349 for rear, but I'd love to know your thoughts and fork length. Awesome channel - thanks from the UK

[@LWTRACER]

355 for the rear. 515 for the front to start.

[@gazasquith758]

@@LWTRACER thankyou sir, I should have watched till the end. All the best

[@nicnadu0515]

Are you running no dust seals on your shocks ?🤔

[@RIDERsxv]

On .90 springs I only get 2mm preload, Is that safe? Rider sag 35mm, 160lbs w/o gear, stock forks. If you're 145lb how can I run stiffer springs without negative preload? All this info is awesome!

[@LWTRACER]

2mm meaning 2 turns of preload? You most likely have preload on the spring even if your adjuster has 0 turns on it.

[@AA-69]

I love your hi-tec measuring equipment .. Is it Mitutoyo or yours mums dressmaking tape 🤔

[@LWTRACER]

The latter. :)

[@Wmrra22]

Would you stick with 345mm rear shock length on a 2nd gen with a KTech, 707 link and 180/55 Pirelli?

[@LWTRACER]

Yup.

[@coldaxle]

What would you say is the performance advantage from going to the gsxr fork swap? Or is it just a race class thing? Im just trying to quantify how much its worth over oem forks with ak20s

[@LWTRACER]

Mainly just class thing, There really isn't any advantage. Stick with stock forks and AKs. There is big flex characteristic between the two and that's rider preference.

[@scottay951]

@@LWTRACER I realize I'm 2+ years late to this conversation, but hopefully you've still got some insight. Do you have any thoughts on going with TWF's fork cartridges instead of the AKs?

[@LWTRACER]

@@scottay951I prefer TWF fork carts over AKs. He gets them dialed in perfectly.

[@scottay951]

@@LWTRACER Glad to hear it, I’m planning on sending my forks up to Zoran in a few weeks to have the cartridge conversion done

[@Audfile]

What I wanna know is, why use the fairing at all? The buffeting even at 100 isn't bad. Does it add a few mph to the top you think?

[@LWTRACER]

Not everyone uses fairings. You dont NEED them. It'll help a bit for mph.

[@johnedwardmcgladdery5071]

What about accounting for the top out spring?

[@LWTRACER]

That's why we measure at full length. and also why these numbers are not the tell all because all forks have different length/stiffness top out spring.

[@johnedwardmcgladdery5071]

@@LWTRACER you're not measuring it at its topped out length unless you use a tool to extend the shock.

[@LWTRACER]

​@@johnedwardmcgladdery5071 I understand that. You would need something to pull it. The weight of the wheel on the forks does some of this.

[@gonzhh95]

@@LWTRACER you can step on it, that get the T O S down.. anyways everybody just wants a magic number for suspension and that just is not posible... by the way great videos

[@julieoliver8170]

Can I get a list of parts for a front end swap?

[@julieoliver8170]

I have an O2 model

[@duainejanes8240]

Sorry I need to not make comments after working a double as my thinking is not correct. You are correct about cartridge kits can change fork length. And I didn't even watched your whole video. Which is bad on my part , I will shut up now and go to sleep!

[@LWTRACER]

You can also modify the existing cartridge to change length. Top out spring, cutting springs, spacers, etc. Cartridge is how you change the length of a fork.

[@duainejanes8240]

You are wrong a cartridge kit does not change the length of a fork, and the same model bike has the same for length forks . And you can definitely use the dropping bike at the triple clamp as to changing the handling of a motorcycle. If you think this is a lie . Then look into Dave Moss using this method on a MT 10 , in which he recommends from 10 to 20 mm of drop. I have use this method myself on my R1 and many bike that I have set the geometry for!

[@LWTRACER]

Cartridge Kits 100% can change the length of the fork. Ask any seasoned suspension guy. Ask Dave Moss. The cartridge is what determines the length of the fork. Remove the cartridge and what happens?
