# Weight Question

I was comparing the new 2006 TC450 to my 2004 model and trying to figure out the weight differences. If you look at the spec sheets for the 2004 and 2005 TC450, they all quote a kerb weight (I assume this means oil, water fluids etc - but NO fuel) of 109.7kg (241.8lbs), remembering that these are all electric start models.

When you look at the new 2006 spec sheet, it shows the TC450 being 100.8kg (222.2lbs). The obvious big change is dropping the electric start whereby they quote in the text a weight saving of "nearly nine pounds", ie 4kg = 9lbs. Now when you do the math, 109.7kg (241.8lbs) less 4kg (9lbs) used to equal 105.7kg (232.8lbs) when I went to skool and got my edumakation.

Now how to they get to 100.8kg (222.2lbs)? Looking at the spec sheets, apart from valves, carb, ohlins shock, 50mm zocks, new tank (same capacity by the way) and new plastics, which I reckon would not result in any significant weight differential between the 2004 and the 2006 models. How do they drop the extra 5kg (11lbs) to get down to 100.8kg (222.2lbs)?

On top of that, how do you account for another 5kg (11lbs) diff between the TC450 and the TC250? I know the 250 has mag engine cases where the 450 has alum, but apart from that they are the same bike. There can't be 5kg (11lbs) in the smaller barrel, piston and crank - surely?

Any clues?

I'd be willing to bet that the difference is found between design weight and manufactured weight. Design weight is what the thing should weigh from the sum of all the parts on paper. Manufactured weight is the sum of what all the parts really weigh when built.

The 250 may not require the gearbox to be as strong etc. If this is the case it would all help reduce the weight..............maybe

Weird Science? - either way, if their claims of 100.8kg for the TC450 and 95.3kg for the TC250 are correct, then the new husky is really in the ballpark weight-wise, which might be enough reason to tip me toward upgrading the 04 to an 06.

Hi!
I unfortunately broke my turn signal switch today and can't seem to find any available other than bike bandit. It's part of the left switch cluser on the handlebars.
The part number for the switch cluster is 800099721
Bike bandit is the only vendor that has it and it is retailing at 125 dollars! Anybody know where I could get a used one or another for cheap?
Thank you for the help!

• Rockstar Energy Husqvarna Factory Rider Starts his Quest to Defend Cross-Country Rallies World Championship
March 15, 2018 – (Motor Sports Newswire) – Rockstar Energy Husqvarna Factory Racing’s Pablo Quintanilla will re-start his 2018 international rally racing campaign on March 24 to 29 at the Abu Dhabi Desert Challenge in the United Arab Emirates. Working hard towards returning to full competitive fitness following a foot injury sustained during the closing stages of the Dakar Rally, Pablo’s teammate Andrew Short is expected to join the Rockstar Energy Husqvarna Factory Racing squad at the 2018 Merzouga Rally in mid-April.

With the Abu Dhabi Desert Challenge playing host to the opening round of the 2018 FIM Cross-Country Rallies World Championship, the event in the UAE will see Pablo Quintanilla begin the defence of his FIM Cross-Country World Championship title. Securing eighth overall at the 2018 Dakar Rally in January, the Chilean rally star is already looking forward to a solid return to racing aboard his FR 450 Rally machine.
Successfully wrapping up his debut participation at the prestigious Dakar Rally with a top 20 result, Andrew Short has been recuperating from a fractured tibia and fibula on his lower right leg. Resuming his training sessions in the middle of March, the American has his eyes set on making a return to racing at the Merzouga Rally on April 15/20, in the dunes of Morocco.
Celebrating its 28th edition in 2018, the Abu Dhabi Desert Challenge is a six-stage-long rally taking place in the southern part of the United Arab Emirates. Kicking off with the traditional Super Special Stage on Saturday, March 24, the event will continue with five more days of racing in the Liwa Desert before competitors reach the finish line inside the Yas Marina circuit on March 29, 2018.

Pablo Quintanilla: “Abu Dhabi will be our first race after the Dakar and I’m really looking forward to it. It’d be good to start the season carrying the #1 plate on my Husqvarna as the reigning champion. With it being the first race for the new season, it is important for everybody. My goal is to get a good race pace from the beginning in order to be inside the group of leading riders. The season will be long and my plan is to continue improving my pace as the racing goes on. I want to get back my racing speed and also remain strong throughout the event in Abu Dhabi. Taking place in deep sandy dunes, the Desert Challenge is always a tough event and it is also highly probable that we will have to race in high temperatures. It’s going to be a challenge but I’m looking forward to it.”
