What is up with the 07???

Recommended Posts

Motocross action did a 10 best bikes of the decade article this month and they said the 2004 thru 2006 RM250 was one of their favorite bikes of the decade. What happened to the RM in 2007 that it wasn't thought of as good as prior years?

I do now.

Features

§ 249cc, 2-stroke, liquid-cooled engine with a bore and stroke of 66.4mm x 72.0mm.

§ An aluminum cylinder core features Suzuki Composite Electrochemical Material (SCEM) for better heat dissipation, improving durability and weight savings.

§ Redesigned the ports for more power output at low- to mid-range power, and offering increased torque at high rpm range.

§ Main exhaust port is enlarged from 42mm to 42.6mm.

§ Sub-exhaust ports are shortened 1mm at the bottom and the timing is advanced by 0.5mm. These changes for better roll-on acceleration at low rpm ranges, more power output in the low- and mid-range power and increased torque at higher rpm ranges.

§ Redesigned the exhaust valves increase roll-on acceleration and power output throughout the rpm range.

§ To add to engine power, the electric CDI is remapped to be more efficient and increases power output at lower rpm ranges.

§ The engine angle is changed and is tipped forward slightly to help the machine gets more traction through the bumps.

§ Strong and lightweight frame and easy-to-remove aluminum rear subframe improve rigidity and performance on the racetrack.

§ Rectangular-cross-section aluminum swingarm produces huge weight reduction.

§ SHOWA inverted 47mm front forks provide 310mm of front wheel travel. With fully adjustable for compression damping, rebound damping and spring preload to suit variety of riders.

§ The upper holder of the front fork protector is now abolished and fixed only at the bottom end to help weight reduction and less friction.

§ Piggyback-reservoir rear shock absorber is fully adjustable for high, low, rebound damping and spring preload SHOWA unit that offers 310mm of wheel travel.

§ Renthal-made aluminum tapered handlebars with Renthal handlebar pad reduce vibration reaching to the rider.

§ Full-floating front disc brake works with dual-piston caliper and rear disc brake with single-piston caliper has high efficient brake pads.

§ Each side of the seat has textured surface for better knee gripping.

It's just that in 04-06 they liked the RM better than the YZ but in 07 to present they like the YZ better than the RM. The 07 and 08 RM is a bit torqier than the 04 to 06 and MXA said in the 07 RM250 test that the more Suzuki tries to be like Yamaha in having a really torquey smooth two stroke like Yamaha has, the more the ball falls into Yamaha's court. It's just politics, really. The 07/08 RMs are just as good if not better. MXA just wanted to reward Suzuki for having a super hard hitting, fast revving powerband. It makes for a better story.

That's pretty much it. There wasn't a thing wrong with the '07 & '08 RM250's, but when they went after the Yamaha powerband in '07 the chassis setup wasn't quite right for that style of riding, but the Yamaha's was. The '04 thru '06 RM250's liked to rip down the straights, cut to the inside, turn on a dime and rip it back the other way. The '07 & '08 had the turn on a dime suspension setup, but it didn't have that quick rev'ing powerband anymore.

So the miss matched engine and suspension gave the title back to Yamaha. Had they continued to do what they knew best, they would have been the best 2 stroke for the last two years ('07 & '08). They were trying to make them respond more like 4 strokes with less of a hit and more throttle control. It works great for me but I've never ridden a YZ250 and with my suspension no longer stock I'll never know why they preferred the handling of the YZ.

Yup the '06's are very good bikes. But we are also talking about stock bikes, start changing pipes and suspension settings and it's a whole new deal.

my '06 tore it up today at a gp. drag racing up steep hills, then diving in to 180* turns and back down to do the same at the bottom. i noticed i could close on some of the guys in the next class up, going in to the turns. now if i could just figure out how to exit with the same speed.....

My 07 feels really good to me. It still has good top end and a good hit. It has a very nice powerband.

I'll agree with that. My 07' is starting to fit me like a well worn glove.

I've noticed that I get less tired and can ride longer with my 07 rm than my 03 cr250. Maybe a little less hit is just what I needed. I'm really starting to like this bike.
