tR1ke on Track

[roadtrackrace]

We took the tR1ke to the track at Everyman Racing and this little video shows just how quickly it can be cornered. Our tame racing driver saw 120mph on the straight and when he really pushed hard into the corners it simply understeered so no stability issues.



Hope you like it...

Looks good! ;D
Any data on g values in the corners?
What tires are you using?

Fab, more footage please

[roadtrackrace]

Tyres are road tyres. Marangoni Zeta Linea on the back for the V tread pattern and Yokohama a 539's on the front.

Quickrack now fitted which makes it a blast on road and track

More footage coming up once we have taken off the race cans as they are too loud for most tracks' db limit. (sound glorious though so it's a bit of a shame and passed MSVA no problem)

Any performance specs?
0-60(mph)?
0-100?
braking distances?
I also think that RTR should really put at least a technical specs page on the website, it will give people a much better idea of what they are buying. Personally, when you guys state 430bhp/ton I would love to know what that translates to in tested performance specs!

I agree, somewhat! I feel it is more important to see figures relating to grip like lateral g's, slalom, lap times, etc. Given the nature of the beast I feel these figures would be more fitting.

However, in RTR's defense...it's still early and I am sure these guys are very busy dealing with orders and design related issues. I commend them thus far and wish them luck and hope to get my hands on one of these beasts in the near future.

I'm not sure tech specs are all that meaningful.
There are so many variables in the construction of a kit and the set up and driving skill that what a good team can get out of the machine probably far exceeds what most kit builders will achieve.

Still it would be nice to have comparisons on track day between the various MEV vehicles on the same track, similar tires, same driver.

Latemarch, your points are absolutely valid. In my opinion, all around specifications are a necessity for selling a vehicle (in my case) across the Atlantic and even online. Now that I think there is only one tR1ke in the U.S. and likely no where near me, specs are becoming increasingly important. Lastly, many amateurs like myself base most on their opinion of the car on its stats, most likely that extremely important "0-60" time.

We haven't got official times for the tR1ke but around the Prestwold Hall track on the 1.7 mile section, it was faster than the Rocket M350.

The tR1ke hits 120mph at the end of the longer straight...!!!

This is largely due to the fact that it hits over 70mph in first gear which if the tyre is hot, you get good traction and you don't light up the back wheel too much it will hit in about 3.5 seconds (in reality quite hard to do though in the same way as it is hard to do flat out first gear acceleration on a superbike).

Where it really impresses though is from 40mph to 120mph because the back tyre stops spinning and you are simply hurtled forwards until aerodynamics start to limit your progress

If you type the weight and bhp of the tR1ke into a calculator it gives a theoretical 2.54 second 0.60mph but the reality is it is closer to 3 seconds if not a tad over. A tR1ke carrying 1 person weighs a similar amount to an R1 carrying two.

We would have been able to do some accurate timing but our track time was curtailed by the wondrous noise emanating from the twin race cans breaking the Db limit at the track just a touch.

I'm impressed with those figures. Is the 195 tire the largest that will fit on the stock swing arm and tire setup? Would it be possible to utilize one of the 240, 300, or 330 wide tire kits that are available on the market for the R1? Most of the wide tire kits are extended in length...how would that affect handling? However, not all of these wide tire kits are extended at all. Unfortunately they are quite expensive. If one could get the power down where it belongs these things would be phenomenally quick...I can't wait to get one! Looking forward to more info.

[hum]

Impressing values! Are there video's made you like to share?

The rear tyre is a car tyre and not a bike tyre. The size that we use is a stock 205-40-17" tyre which is a very common tyre size available in hundreds of different compounds including things like super sticky Toyo R888's. We currently run it at 18 to 20 psi pressure (still experimenting a little) which makes sure the contact patch is very flat giving a lot of grip.

So you feel the 205 is wide enough? I realize that one wants to keep the weight down as much as possible on an outfit like this. Just wondering if the vehicle would benefit from wider rubber out back. I trust you guys if you say it is sufficient!
