Triumph 675

[drftsub]

Id say the fact that it is physically smaller, much more narrow than a typical 600, heavier internal components will attribute to the engines characteristics more than overall vehicle weight ( and the fact that even tho the pistons etc are heavier due to the larger bore there is still only 3 )

just my $.02

Correct...

Where did you get 20 pounds lighter??? quote SportRider on actual dry and wet weights...


675 Triumph.......389 417
Yamaha R6.........396 423
Suzuki GSXR600 411 438
Kawasaki ZX6....403 430
Kawasaki 636.....404 431
Honda CBR600....402 431

I think you'll find that the weight savings are components rather than engine...

I was comparing the dry and wet weight of the 675 to the GSXR 600 which I thought was typically one of the lighter bikes.... I guess I'm a little outdated. But even by your numbers the triumph is about 20 lbs lighter.

I'm new here, but I own a Graphite 675. It was a blind purchase and the best one ever made. I LOVE this bike, the handling is tops and the stock tires are Pirelli Dragon Supercorsa Pro which makes for nice traction. Tq is right from the get go. I did a dyno breakin and came out with a reading of 114 HP and 51 ft lbs of tq.

It may not have the top end that the jap 6's do but that doesnt matter for street. As for track, the jap mfs have the money to put into r and d. This is still a relatively new model and it is just starting to gain popularity in the aftermarket scene which has affected its racing development

The AMA cleared the 675cc triple for racing in the Formula Xtreme class starting in 2007 and didn't have a factory backed racing team until 2008, in the British Supersport Series. When people start racing the bikes, the aftermarket starts developing cool parts.

Since it was a new model in 2006, it took quite a while to get anything made for it aftermarket wise. From windscreens to slip on exhausts. Not to mention the cost factor. Which is easily double the price from most of the jap 4 aftermarket bits. Triumph did not even want a factory team due to the R & D costs and other financial demands. You are correct that with people interested in racing it the parts will come. But a factory backing from the get go and solid affordable parts would've made the entry of this bike way easier.

And like I said it is still a relatively new model with only 4 yrs under its belt. The first unveiling was in Sep 2005, when I put a deposit down to hold a bike from the small shipment to the U.S. there wasn't even a floor model to look at.

Are you sure they are the Pro and not the SP??? SP stands for Sport Production... see pic

You're looking at the Pirelli's that come stock on some Ducati 848 and Triumph 675
and are labled 'SP' or sport production compound... they are only available
through a Ducati dealer or Parts Unlimited... Most importantly they are
designed for the street and the temperature ranges you would expect to
encounter on the street... I paid $600.00 for set and never regretted the
cost...

What they deliver is the best of both worlds... the DOT race tire's accuracy
of line and confidence in grip... coupled with the Street tire's envelope that
has been stretched so that it reaches the operating temperature range
earlier... plus it operates over a wide temperate range plus unlimited heat
cycles...

Mr.RC45's 180/55 Pirelli street tire... someday I'll take them to track...

When I purchased my bike. It came stock with the Pirelli Dragon Supercorsa Pro's and not the SP.
