El otro día me dijeron como pesar la moto. Después de dar mil vueltas buscando donde me la podían pesar la solución era tan tonta como pedirle una balanza a mi vecino… ya se me habría podido ocurrir a mi…
He puesto dos básculas domésticas, una en cada rueda. La delantera ha pesado 100 kgs y la trasera 101. A esto le he sacado 1.200 grs. que es lo que pesan los soportes de las maletas, por tanto:
– Llena (con líquidos y 24 litros de gasolina): 100+101-1,2= 199,8 kgs
– Vacía (con líquidos y sin 18,24 kgs de gasolina: 181,56 kgs (densidad de la gasolina 0,760).
Según Yamaha pesa 208 llena y 185 vacía así que según esto le he sacado unos 8 kgs llena y menos de 4 vacía.
Este es el detalle de los pesos que he ido controlando:
1. Peso añadido (en gramos):
Parrilla porta equipajes OTR: 674
Cubrecarter OTR: 1.882 – 797 serie = 1.085
Protector faro: 137
Tapones basculante: 45
Ampliación pata cabra: 50
Instalación GPS: 100
Guardabarros alto: 623 – 575 serie = 48
Amortiguador dirección Scotts: 696
Estribos Pivot Pegz: 730 – 530 serie = 200
Cubremanos Acerbis: 800
Puños calefactables: 334 – 50 serie = 284
Power Commander: 180
1. TOTAL AÑADIDO: 4.299
2. Peso sacado (en gramos):
AIS: 394
Estribos pasajero: 1.860
Sensor pata cabra: 94
Asa arrastre moto: 222
Cola soporte top case: 146
Guardabarros trasero: 1.716 – 476 luz y portamatrículas OTR = 1.240
Escape serie: 6.150 – 1.888 Akrapovic carbono = 4.262
2. TOTAL SACADO: -7.824
DIFERENCIA 1 – 2 = -3.525 GRAMOS
3. No tengo los pesos de los conjuntos delanteros (barras suspensión/rueda/disco/tijas/manillar) actual y de origen y por tanto no puedo compararlos pero lo lógico es que haya sacado bastantes kilos ya que hay un sólo disco y pinza de freno mientras antes habían dos. Solo la pinza y latiguillos suponen un ahorro de más de 1 kg. También el buje y llanta son más ligeros que los de origen pero no tengo ni idea de si lo son las barras y tijas mecanizadas.
4. Tampoco he podido pesar la rueda trasera de 18″ pero en este caso no creo que haya variado gran cosa respecto a la de 17″. La llanta y neumático son más grandes y los radios más gruesos y pesados pero eso debe quedar compensado por el buje y la corona más ligeros.
5. La moto la he pesado con mousse delantero, cámara super reforzada detrás y cubiertas que pesan bastante más que las de origen además de algunas protecciones y pequeños accesorios.
En resumen: Parecería razonable pensar de que a pesar de haber añadido algunos componentes y que otros sean más resistentes y pesados que los de origen, el ahorro total esté de 8 a 10 kgs.
The other day I was told how to weight the bike. After cruising around looking for where I could weight it the solution was as dumb as to borrow a scale from my neighbor…
I’ve placed two domestic scales, one on each wheel. The front has weighed 100 kg and 101 rear. I have the luggage brackets that weigh 1,2 kg. so:
– Full (with 24 liters of gas and rest of liquids): 100 +101-1,2 (luggage brackets) = 199.8 kgs
– Empty (without 18.24 kg gas): 181.56 kgs (density of gasoline 0.760).
According Yamaha, the 660 weighs 208 kg full and 185 kg empty.
This is the detail of the weights that have been controlling:
1. Added weight (in grams):
OTR luggage rack: 674
OTR skid plate: 1882-797 OEM skid plate = 1,085
Light protector: 137>
Swing arm axle caps: 45
Side stand extension: 50
GPS Installation: 100
High fender: 623-575 OEM = 48
Scotts steering damper: 696
Pivot Pegz: 730-530 OEM = 200
Acerbis hand guards: 800
Heated grips: 334-50 OEM = 284
Power Commander: 180
1. TOTAL ADDED: 4,299
2. Saved weight (in grams):
AIS: 394
-Passenger footrests: 1,860
-Side stand sensor: 94
-Front bracket to pull the bike: 222
-Top case grill: 146
-Rear fender: 1716 – 476 OTR license plate and rear light = 1,240
-OEM Exhaust: 6150 – 1888 Akrapovic carbon = 4.262
2. TOTAL SAVED: 7824
DIFFERENCE 1-2 = 3.525 GRAMS
3. I don’t have the weights of the front sets (bar suspension / wheel / disc / seatpost / handlebar) so I can’t compare the OEM and the actual, but I think I removed many kilos as there is a single disc and caliper. Only the caliper and hose represent a saving of more than 1 kg. Also the hub and rim are lighter than the original but I have no idea about the OTR triple claps and YZ bars compared with the OEM.
4. I don’t know also the weight of the 18 «rear wheel but in this case I don’t think it has changed much compared to 17». The wheel and tire are larger and the spokes are thicker and heavier but that should be offset by the lighter hub and rear sprocket.
5. I’ve weighed the bike with a front mousse and super thick rear tube that weigh considerably more than the original plus some protections and small accessories.
In short: It would seem reasonable to think that despite having added some components and others are more resistant and heavier than the original, the total savings is 8 to 10 kgs.
Muy bueno el detalle Jaume y me alegro que hayas cumplido con el objetivo de aligerarla.
Saludos.
Bueno… no tanto como me habría gustado pero algo es algo 🙂
Fully loaded below 200kg is a good target 🙂 Mine is almost standard and with original yamaha/shad boxes but it definitely feels a lot light than my previous ride – a 1993 750 super tenere . I’ve had to lift the old back on two wheels on several occasions and also tried that exercise with my new little pony 🙂
I know, I had a Super Tenere 1200 and was very, very heavy. The 660 is a good compromise but it could be fantastic with 170 or 180 kg…
It worked!!! Can’t believe it. 🙂
Really interesting. That’s a lot weight what you saved!
I was hoping to save more. If you think all the money invested just for 3,5 kgs… The good thing is that all the new components work much better than the OEM, this is more important than the weight saved.
I’m sure it drives fantastic. You can’t do much more I think. Would be interesting what makes really the weight-difference between the xt660 and the KTMs and Co. Is it the engine that is so much heavier or the frame? Maybe everything a little bit more build for reliability. I had long ago a KTM LC4 but it was a nightmare. I’m sure they are much better build now but I still not trust them 100%. 🙂
Yes, it drives very well but I don’t think I can do more in this bike. Too complicated and expensive to lighten it more. The only thing I can do is to increase power with a big bore…
KTM says the 690 is 139 kgs empty. To compare it with the Tenere you must add about 19 kgs of gas. This is about 160 kgs full. 40 less than the Yamaha. But also a big tank is heavier, the windscreen, proper light, rear frame… the old engine of the Yamaha must be a lot heavier than the KTM…
I really like the KTM’s but as you I’m not trust them 100%.
