85cc MX Jnr.

The 'all new for 2013' 85cc MX machine has taken the world by storm and this absolutely stunning looking bike with its unmatched high specification of standard production components and performance only receives minor updates for 2014. These updates include a new piston design with changes to both the cylinder configuration and engine set-up. these changes make for better engine performance and longevity in the harshest conditions. New suspension settings also feature for both the front forks and the rear shock absorber with adjustments to shim settings, oil weights and volumes and shock gas pressures, all working together to give a much better progression to the suspension units of both the small wheel and big wheel variants. The machine also receives a fresh look with a new decal kit in an Italian theme.

125cc / 144cc.

The already well proven TMEES 125cc / 144cc engine has also been treated to a thorough overhaul, the original 2012 125cc TMEES engine received a major overhaul for 2013 including new crankcases with a revised induction angle for the V-Force reed block. a new air boot and air filter system. new exhaust system and a new main bearing set-up to reduce drag and increase engine responsiveness, in 2013 the 144cc engine was also revised to these specifications. For 2014 TM Racing have yet again increased the performance of these incredible engines and have found gains in both power and torque across the rev range with an all new twin-ring piston design which increases compression stability with less blow-by under extreme conditions, new cylinder port timing to maximise the potential of the new piston and new exhaust valve pulleys fitted with new larger diameter command cables to increase the performance and reliability of the TMEES system, all working harmoniously with new carburetion settings. The chassis also features some revisions and these include a new triple clamp offset combined with new forks and shock settings to enhance bike stability and turning making for a better handling package, in the aesthetics department there is a new decal kit and matching seat cover once again following an Italian design.

250cc / 300cc.

The mighty 2 stroke flagships of the TM Racing range have now been brought in line with the 125cc and 85cc engine induction alterations, after both receiving the new air boot and air filter design in 2013 the large capacity 2-Stroke engines have been re-worked and feature a new crankcase design with a rotated V-Force reed block position, this is matched to a new inlet manifold with altered carburetion settings these changes, now combined with the 2013 intake system, maximise throttle response and engine performance across the rev range. As the 125 the 250cc / 300cc machines chassis feature similar revisions, again these include a new triple clamp offset combined with new forks and shock settings to enhance bike stability and turning making for a better handling package, in the aesthetics department there is a new decal kit and matching seat cover once again following an Italian design.

250Fi.

The stunning TM Racing 250Fi machines will also receive some changes for 2014 and after having months of testing at the highest levels of competition in the MX and Enduro World Championships the latest updates to the 250Fi engines come from development of the TM Factory Racing Teams. The 2014 engine will receive a new piston with an all new crown design for better burn control, power output and efficiency when combined with the new cylinder head shape with altered volumes. New EFI mapping settings for both ignition timing control and fuel injection control work in tune with the new head and piston arrangement to increase power and torque for a large part of the rev range and these changes are different for both MX and Enduro variants too. Both the MX and Enduro engines have unique pistons and head profile variants to give the performance required for each discipline, on the MX engine and new inlet camshaft profile and a new larger diameter throttle body feature and increase the performance values even further to suit the harsher nature of Motocross. Whilst the Enduro engine retains the smaller throttle body and 'relaxed' camshaft profiling to give a smother, broader power output better suited to the required conditions found in Enduro. Once again the same changes feature on the chassis department, these include a new triple clamp offset combined with new forks and shock settings to enhance bike stability and turning making for a better handling package, in the aesthetics department there is a new decal kit and matching seat cover once again following an Italian design.

450Fi.

The mighty 450cc engine has once again proven to be a world beater in many disciplines and for 2014 the philosophy is simple, small changes. For 2014 the 450cc engine receives only minor alterations to ignition timing and fuel control via the ECU and a small change to the piston design to enhance burn control and efficiency. The already immensely powerful and torque laden engine required little in the way of more performance and simple alterations have just improved its responsiveness at lower rpm's and facilitated easier starting on the conventional kickstart variants. As with the rest of the TM Racing range the chassis receives the same changes, these include a new triple clamp offset combined with new forks and shock settings to enhance bike stability and turning making for a better handling package, in the aesthetics department there is a new decal kit and matching seat cover once again following an Italian design.

Full specifications, model images and prices for 2014 models will be available soon.

Por lo que se entiende no hay demasiadas novedades... me parece que el pistón biaro en las 125cc y 144cc es un paso atrás en cuanto a potencia. Tengo ganas de ver ya alguna foto!

TM Spain, actual importador de las especiales motos italianas TM, nos informa de que ya están disponibles los nuevos modelos de TM Racing gama 2014, tanto la Enduro, como MX y Supermoto.

Los cambios más importantes que encontramos en los modelos 2014, son los siguientes: En todos los modelos la parte ciclo, dispone nuevo offset de las tijas de suspensión, junto a nuevos setting del amortiguador especifico TM. La funda del asiento es nueva, así como el diseño gráfico de la decoración de su carrocería que varía mínimamente.

En los modelos tanto de MX como de Enduro de 125cc, encontramos a nivel mecánico, nuevo pistón con dos aros extra finos, nuevo cilindro, válvula de escape modificada, y nuevos cables de accionamiento de la válvula electrónica.

En la 250 Fi 4T, de MX y de Enduro, estrena nuevo pistón, junto con una nueva cámara de combustión diseñada para incrementar la compresión, diferente mappings de la inyección.

En las 250cc y 300cc 2 tiempos, tanto de Enduro como de MX, la principal variación es la recolocación de la caja de láminas y el montaje de un nuevo colector de admisión.

144cc

Por poco espesor que sea, es x2. De siempre en los motores de 2T para ganar algo de potencia (sacrificando mantenimiento, eso sí) se han puesto pistones monoaro, que no venga nadie ahora a inventar que los biaro son para dar más potencia.

Durarán más ya que tendrán menor desgaste al ser dos y la moto será más progresiva, pero no tendrá mayor potencia. En enduro aún se puede medio entender, en MX no.

Un segmento o dos no tiene nada que ver con la potencia y si con el rozamiento..ellos están buscando un motor más lineal y lleno, si quieres más sobrerégimen y un motor más perezoso abajo, le pones monoaro y ya.

Como digo, la la potencia no tiene mucho que ver con el numero de aros, tiene mas que ver con la distribución del cilindro.

Ya, ya, está claro que lo que marca el cáracter y la potencia es la distribución del cilindro, pero a más rozamiento, menor potencia, por lo que el biaro es peor (almenos en mi opinión) que el monoaro... Eso sí, tiene más línealidad como bien comentas y es menos mantenimiento, pero yo prefiero más prestaciones y mayor mantenimiento!
