2020 Glen Helen 2 EnduroCross Race Report

  2020 Glen Helen 2 EnduroCross Race Report Colton Haaker extends point lead with second victory of the season.“I had a huge crash in practice because my holeshot device didn’t release, then I crashed during the Hot Lap, but still managed a fifth place,” Haaker remarked. “The first race was going good, but I got taken out trying to lap Wally Palmer, so I dropped back to third. The second race was much better as I worked my way into the lead and did my thing to the end. And then the holeshot in the final moto helped me get the win. The red plate is heavy and defending the title is heavy, but I am happy to get off to a great start to the season.

Overview

The 2021 KTM 450 SMR looks to break the often expensive and time-consuming barriers of entry to supermoto racing as a dedicated racebike that’s available at the dealership. KTM took the highly potent 450 SX-F motocross platform, fitted it with supermoto-specific components like Brembo brakes, Bridgestone racing slicks, and a Suter slipper clutch among other bits, and cut it loose for closed-course supermoto racing. And it’s ridiculously fun.

Powertrain: Engine, Transmission, and Performance

KTM 450 SMR used the same 450cc, SOHC, liquid-cooled single as found in the 450 SX-F motocross platform, which last produced an impressive 54.8 hp at 9,500 rpm and 34.6 pound-feet of torque at 7,400 rpm on our in-house Dynojet 250i dyno. Internally, KTM mated a supermoto-specific Suter slipper clutch to its five-speed gearbox for consistent deceleration.

After two years on the FMF KTM Factory Racing off-road team followed by several seasons on Hondas in Baja, he’s transitioned to the next phase of life where family is the priority, gladly accepting his role as self-proclaimed “Mr. Mom” for young son Kobe, which allows wife Rhiannon to concentrate on her many business responsibilities.

Based off the ’21 450 SX-F motocross bike, the 450 SMR swaps its moto hardware for a purpose-built and competition-specification road setup. After a seven-year hiatus from KTM ’s North American motorcycle lineup, the new and improved 2021 450 SMR (,299) returns the Austrian bike

Road Test Editor Michael Gilbert noted in his First Ride Review, “The 450 SMR has smooth, predictable power delivery at corner exit, which makes for deceivingly fast straightaway speed. At first touch of the throttle, the KTM offers crisp, tractable acceleration before rocketing off the corner with the front wheel pointed skyward.”

Handling

The KTM 450 SMR shreds tight kart track layouts with serious conviction, with an incredible balance of agility and confidence-inspiring composure. The Bridgestone Battlax racing slick tires offer seriously impressive amounts of grip, while the feel and performance of the WP Xact suspension suit the needs of supermoto well.

Brakes

A top-shelf Brembo M50 four-piston Monoblock caliper clamping to an oversize 310mm disc brings the 450 SMR to a serious halt, with great feel at the lever.  A single 220mm wave rotor and single-piston caliper handle rear braking duties.

Fuel Economy and Real-world MPG

Claimed or measured mile-per-gallon information is not available.

Ergonomics: Comfort and Utility

KTM struck balance in a well-proportioned rider triangle with a narrow midsection at the radiator shrouds. The Neken handlebar is a touch wide for our liking, especially in head-down roadrace position. Seat height is a claimed 35 inches, which is significantly lower than the SX-F motocrosser’s measured 37.6 inches due to the reduced suspension travel. At 5-foot-7, Road Test Editor Michael Gilbert found it comfortable at slow speeds and stops.

Electronics

The KTM 450 SMR comes equipped with two selectable engine maps, which tailor power delivery. A traction control aid is also equipped, and can be disabled. Both the engine maps and TC can be changed on the fly via buttons located on the left handlebar.

A launch control map is also equipped for race starts.

Warranty And Maintenance Coverage

No warranty information is available.

Quality

Fit and finish quality of the 450 SMR is second to none. KTM fitted the platform with only top-shelf supermoto specific components, like the Suter slipper clutch, Alpina wheels, and Bridgestone Battlax racing slicks.
