V8 Motorcycle Transmission Developed

Tuesday, September 8, 2009
Sabretooth Motorcycles V-8 engine
Many of the problems with plugging a V8 engine in a motorcycle frame is transferring all that power to the rear wheel. The new V8 motorcycle transmission developed by Sabertooth Motorcycles and Taylor Race Engineering aims to solve that dilemma.
Sabertooth Motorcycles, created in 2005 by Dr. Ben Daniels, is pleased to announce it has entered into a partnership with Taylor Race Engineering, the premier supplier of specialty transmissions for high-powered race vehicles, to develop a new multi-speed transmission for all Sabertooth V8 Motorcycles.

This will be the first transmission designed and engineered specifically for use in a motorcycle that can handle the torque and horsepower generated by a V8 engine.

“We are very excited to be working with Sabertooth Motorcycles on this project,” said Mike Watson, CEO of Taylor Race Engineering. “Dr. Daniels’ idea of ultimate performance is in line with our own vision and we are thrilled to be the first company to design a multi-speed, purpose-built motorcycle transmission for a V8 motorcycle.”

The new DynaClaw transmission will have 4 forward speeds and an electric reverse and will be used with a Gates Polychain carbon GT belt drive or a 630 chain drive on select models.

The approximate transmission overall gear ratios are:
1st: 9.2:1;
2nd: 5.5:1,
3rd: 3.3:1;
4th: 2.2:1.

The new DynaClaw transmission will be available in two standard configurations: as a manual transmission with a lightweight pull hydraulic clutch or as a clutchless transmission with a torque converter.

Sabertooth expects to have the transmission available for delivery in motorcycles by the second quarter of 2010.

“In V8 motorcycles, the transmission has traditionally been the weak link, said Dr. Daniels, owner of Sabertooth Motorcycles . “Transmissions used in other V8 motorcycles are notoriously fragile and limited to either single speed or two speed configurations. The DynaClaw transmission will be the first multispeed transmission designed specifically for the power, torque and weight of a V8 motorcycle and I couldn’t think of a better company than Taylor Race Engineering, with their years of specialty race transmission experience and engineering, to help us develop it.”

About Sabertooth Motorcycles

Sabertooth Motorcycles, created in 2005 by Dr. Ben Daniels, offers an alternative to huge V-8 powered bikes, v-twin bikes and other high-performance motorcycles.

Sabertooth Motorcycles operates a 20,000 square foot factory in Piedmont, South Carolina with in-house frame building, sheet metal fabrication, paint operations and assembly. The company’s proprietary frame and swingarm design has undergone extensive finite element analysis (FEA) testing to ensure structural integrity of the components under stress.

Sabertooth Motorcycles uses Ford Racing engines in its bikes, selected for their smoothness, reliability and awesome power.

Outsourced components from high-end brands have been developed to Sabertooth specifications in many cases.

Doesn't a stock ninja zx10 send 200 hp to a lightweight transmission anyway? Is all this additional power going to hook up with the pavement?

I have been looking to buy any transmission to fit a small block chev eng on a bike anyone know where i could get one email me at scraper_blazer@yahoo.com thanks

I like what your doing mine high gear only works fine Keep up the great work

I think anyone who does not own a v8 bike shouldn't comment on something they don't understand. Firstly the tranny ratio is just fine, its so similar to Boss Hoss that a couple of teeth difference won't make a difference in RPM/Torque Secondly a Boss Hoss handles,great and there is nothing to wide about driving a v8 bike and I have a 611 HP 502 big block and drive it hard on the street and on the strip and I have never had to change a broken belt yet!! Belt drives made by a quality manufacturer will not break with too much Horsepower. I wish Sabertooth all the best with their cool design.We need more V8 riders and I have to say once you ride a V8 then go back to a HARLEY the Harley feels like a dinky toy!!
A.P.Godwin -Trannie gearing  October 30, 2009 04:16 PM
I agree, the 1st and 2nd gearing is way too low, one will start shifting at 5 mph. Final drive should be about a 1 to 1 or less. With the advertised horsepower to weight, performance should be more than acceptable at highway speeds in 4th gear.
D. Wayne -Can you choose trans ratio's?  September 10, 2009 10:03 AM
These ratio’s read more like final ratio’s through the entire drive train not transmission ratio’s. It also seems like first gear is meant to pull tree stumps not accelerate a high powered light weight bike. Wouldn’t you prefer a closer ratio gearbox even for street cruisin’?

You're concerned about a wide belt on a V8 motorcycle? The entire package is too wide.
x2468 -belt drive?  September 8, 2009 04:43 PM
Is a belt drive really the best way to transmit power from a v-8 to a motorcycle tire? I was told that belt drives can only handle so much hp/torque before they had to be impractically wide to avoid failure.
