Gearing
What size sprockets are you running for spirited riding and track
days. Gearing where second gear clutched wheelies are not ou of the question. I'm pretty sure my bike is stock gearing or geared taller. At 90mph in 6th gear I'm at 4200 rpm. I'm geared way too tall. Suggestions? |
A lot of people like 15/43. Stock is 16/41. I recently made the change. It seemed a little too low at first. Got used to it and now I love it. Second gear no clutch wheelies are a snap on my bike. Your results may vary.

I personally don't know how these guys ride with 15\43 gearing. 1st must be all but unusable but too each his own. I run 16\43 and with that gearing the bike can pull to red-line in 6th plus the added bonus of you can still run the stock 102 link chain and it will shorten the wheel base by around 5mm for quicker turn in. But like always YMMV. ;)

I was at 16/43 for a little while. It was alright. Definitely better than stock. I like my new set up much better.
I wouldn't say first is unusable. Getting pretty close though. The higher gears feel so much better now though. |

So, IMHO, running a 15\43 set up would make 1st all but unusable and I like having a 6 speed. Another advantage of 16\43 is that the speedo error is right at 10% so it is real easy to do the conversion in your head without the need for a speedo healer. This is all just my personal opinion and take it for what it is worth. Keep the motor above 6k and it will pull just fine without the need to gear so low you start loosing the ability to use all the gears. |
For a VTR to ACTUALLY turn 4200 rpm at 90 mph in 6th it would have to be geared 20% taller than stock- a 17 tooth front and 38 tooth rear- which I doubt this is.
AND, the speedo healer would have had to correct for the change 'cause changing sprockets doesn't change rpm at mph. Best way to determine your situation is to simply count the teeth on each sprocket. |

Yea yea yea.
If so, the smart, quick, easy and cheap thing to do is buy and install a 43 tooth rear sprocket. That puts your gearing in line with other sport twin liter bikes and in my opinion is the best gearing to have on the VTR. |
I found - one + up one works REALLY well!!
|
What size stock chain and sprockets are on the thing? 530 or 525? Anyone have some spare sprockets in that size they aren't using and want a few bucks for?
|
530 if it is still in stock form.

Speedo Healer function
So I’m going to change my sprockets to 15/43. I really don’t care what the Speedo says. I can’t read it anyway. I have a 03 superhawk. My question is about the Odometer, will my bike rack up more recorded mileage. Or will it be the opposite... will I record less actual mileage without the speedo healer???

I'm going to order a new 520 chain and sprockets set. I will get
the 43 rear and a 15 and 16 front. I figure throw the 16 on there when I decide to log some heavy miles in July. I have a 3 thousand mile trip planned down to the Appalachians. |
