MSRH VTtwins Advice

To those of you who ride Vtwins I have a question about your tactics and thoughts on them at MSRH.

When running CW going into Diamonds Edge and/or Sugar and Spice I typically get set up for these turns by getting on the brakes while down shifting into 2nd and tip in with about 5.5-6k on the tach. I get to take advantage of a little engine braking and easing off the brakes onto maintenance throttle. The bike is stable and makes good power here so when I get back on the gas after apex I'm right is the sweet spot of the torque band and I get a really good drive off the corner. I find though I have to quickly short shift into 3rd before the next little corner or I run into the limiter at or just after the apex of the next turn. My bike is in standard shift config so I donít want have to shift while in a left hander.

I also notice I can go into these turns in 3rd with about 4 to 4.5K or so on the tach, with less engine braking and the bike has the torque to just chug out of the turn and I can run all the way to redline all the way to my braking marker for the Launch and or the Carousel . I don't feel like I get as good a drive out of the turn doing it that way though, especially when trying to get by someone coming out the exits there. It just doesn't feel like the bike is accelerating as hard as it does exiting in 3rd as it does in 2nd, even though its probably safer.

I'm still getting used to the bike and I'm a novice anyway with a slow guy on fast bike reputation to maintain so with all the traffic in that group, its hard to tell how slow my times would actually be with clear track ahead of me.

So all of my Vtwin ridding brethren & sisterren, what's your approach in these corners and could you explain why if you'd don't mind me asking? Thanks

Are you running stock gearing? You may need to make an adjustment to move your RPM at the speed you traveling. What gear do you get up to on the back straight? Also you could try going faster through DE in third

Stock gearing.

Back straight depending on how poorly I screw up the Bus stop, I just touch fourth but could just as easily carry thrid the whole way and sit on the redline instead of short shifting.

I'll work on that...

Don't laugh, I ran a 1:36.2 last year on a member day run 3rd through Diamonds Edge.

Gp shift plus quickshifter...

Coming out of sugar and spice you can make the line so there is a little straight before flopping over to the left. You should be able to shift there into third and keep a good drive out of there.

In diamonds edge I would do second and figure out a way to shift when needed.2nd should take you far enough into the straight so you can then shift into 3rd.

Like he said above a change of hearing might help. That bike has crazy tall gearing so going -1 in the front or +2 in the rear might help in just staying in 3rd.

Exactly what I meant. If your hauling the mail around MSRH like you Whoop I'm sure that pace would allow you to run in third through DE and not drag the motor to far down the band. I was just poking fun because its easier to adjust gear then grow and fly through some corners faster for a better drive.

If you really want to figure out MSRH you should sign up for a Whoopie Day

I need to do that, I ran a 1:52.9(PR) this last race weekend and need to drop 6 seconds before I can hang with the back of the pack.

The hard part for me is staying in the gas while transitioning directions and not braking going into the dog leg before diamonds edge and into the carousel. I could use some help on corner speed as well.

At MSRH in order to go fast you have to be able to shift up through gears to go fast.
Like through T14 Gut Check, T7, and T3

With my big feet, I go ahead and short shift before or after, so I'm not forced to stick my foot under the lever while leaning over if I don't have to. GP shift would be just one more thing to think about for me right now.

So, I don't track my bike yet but I am just reading all of this. I always wondered why the GP shift was favored. Is that to keep your foot higher off the ground in a turn?

I'd chime in but I'm thinking a SV650 doesn't compare that well with the big Buell... I could be wrong though....

I like to have about 7K minimum on the tach for ok power on the SV hauling my 235 pound around. I will short shift it to delay a shift further down the track, but running the SV out to redline is a waste of time power-wise anyway as it levels out just past 10K.

I run standard shift with quickshifter and running CW race direction and don't have anywhere on the track where getting my big TCX boots under the shifter is a problem. Through gut check I'm off the bike enough that it's pretty upright anyway for that one.

I'm far from the fastest SV out there but I run 1:49's

It's just a lot easier and more natural to hit the shifter down mid turn instead of hooking your foot underneath and pulling up.

Classax switch to gp and ride around the street. Soon enough it will become habit and you won't have to think of it. A good way to remember is while you are down and tucked then hit down. If you are up in the wind then pull up on the shifter. Or after you try it and don't like it then switch back.

Also quickshifters are amazing!

GP Shift + Quickshifter = DA BOMB!

I ride my KTM everyday on the street in standard. Funny thing is I always find myself trying to shift GP. Then when I get the chance to ride the yamerham(GP Shift) on the track I never once try and shift standard.

Because GP seems more "intuitive"

I think you need more teeth on that rear sprocket. It's nice being lazy with long gears on a big litre twin, but you're missing out on significant time if you're only using 3 out of 6 gears on the tranny.

This. You may need to experiment with various different combinations between your front and rear sprocket for each track you visit.

Thanks gents. The bike is definitely geared way tall. I may consider GP shift conversion. Its not that big a deal for me at MSRH.

Xray I think you hit my question on the head. On the 636 anything below 8k or so and it would lug. On the RX it won't lug until you're below 3.5k. Power peaks around 10k and stays strong to 11.5K redline. Life is good when its spinning at 5k and up!
